General TRIOS
• File > Open dialog: Preview and thumbnail support of last displayed graph in Windows Explorer File
> Open dialog. NOTE: Files must have been previously saved in TRIOS V2.6.
• Procedure naming improvement: A procedure can now be named while it is set up in an experiment. If
you save a procedure and change the filename when you save it, you will receive a warning that the
filename is different from your procedure name and you will be able to verify that they match.
• Graph X-Y values: In addition to the tool tip that appears when you hover the cursor over a point,
when you click on a point, the value will appear on the Status Bar to the left of the clock. Once a point
has been selected, the cursor keys can be used to move back and forth along the curve.

of 83
• Graph axis fonts: All axis variable fonts are linked and can be changed at the same time using font size
setting on the Graph >Format tab. The tick mark label fonts are also linked and can be changed in the
same way. Format font size also works for title, annotations, analysis, and any combination of selected
text.
• Graph context menu: Draw removed and Show legend added
• Derivative: Moved from Graph > Edit to Graph > Analysis tab
Discovery Hybrid Rheometer
• New instrument firmware
• New procedure step: Conditioning Electrorheology (available when accessory is installed)
• Zero gap by axial force added as an option
• Transient data collection added to standard controlled stress oscillation
• Global axial force conditions are now recorded in results file and can be viewed in the Parameters list

of 83
ARES-G2
• New instrument firmware:
• WinCE - NK.bin
• WinCe - NKLX.bin
• AresG2 DSP - AresG2hb.ldr
• RsaG2 DSP - RsaG2hb.ldr
• Enhanced Arbitrary Wave test procedure: The Arbitrary Waveshape test now allows the definition of
the strain and temperature history by supplying one or more equations for strain and a temperature pro-
file as a function of time. Up to four individual equations (defining a zone), each with a specified dura-
tion, can be used in one step. The temperature profile consists of up to four isothermal or ramp zones.

of 83
• End of Test (EOT) Conditioning step: The End of Test (EOT) conditioning step is now available for
the ARES-G2. The EOT defines the instruments settings for environmental system, transducer, motor
and stage control after the procedure is completed.
Note that the end of test condition step is a passive step and sets the conditions when the test is
terminated, either normally, or by the user or the instrument. If you want the end of test conditions
applied even if the test is terminated prematurely, the EOT conditioning block should be placed at the
beginning of the procedure. If it is desired to change the EOT conditions based on when the procedure
is terminated, more than one EOT can be used in a procedure. The position within the procedure in
reference to the step when the procedure is terminated defines the EOT conditions that are applied.
With the addition of this new step, the End of Test Options that were previously accessed from the
TRIOS Options menu have been removed.
• Other enhancements and fixes:
• Trim gap implemented for cones
• Temperature ramps for fluid bath repaired
Discovery DSC
• Minor bug fixes

The Wizard steps you through the procedure to generate a Master Curve.
• Curves can be added and removed after starting a TTS session
• The Master Curve temperature is now included as part of the step name and can now be created at
any chosen temperature using the WLF or Arrhenius model to shift the data.

Discovery TGA Instrument Support
TRIOS V2.3 includes support for the new Discovery TGA instrument.
Guardian Option Support
A new option is available for the TRIOS software - TRIOS Guardian™. TRIOS Guardian allows the user
to restrict access, set user levels, and record analysis events. Designed primarily for laboratories in
regulated environments, these tools aid with 21 CFR Part 11 compliance. In addition, TRIOS Guardian
provides options for laboratories and users who wish to define specific access rights as well as restrict
calibration, method development, and/or data manipulation routines.
Key features of this functionality are below:
• Restricted Access to Authorized Users: When TRIOS Guardian is enabled, a TRIOS System Admin-
istrator can restrict access to various features within TRIOS Software, thereby defining the authorized
user list. The user list is coupled to work with all local and domain-based Windows user accounts.
• User Levels: Within TRIOS Guardian, each authorized user is assigned either a Standard User Level
or a Basic User Level.
• Audit Trail: The TRIOS Software Notifications pane provides a computer-generated time/date log of
events (inherent to the software), including Windows User ID.

Miscellaneous–TRIOS General
Performance Enhancements: As we develop instruments with increased capabilities, performance
enhancements have been implemented to ensure high data sampling rates are handled smoothly by TRIOS.
In addition, very large files may now be generated that require higher amounts of internal computer
memory to process. As a result, you may now notice that on occasion, TRIOS automatically closes results
file tabs that have not been viewed recently; this occurs if memory runs low, thereby preserving system
performance. To restore the tab double-click the results file in the File Manager.
TA Explorer: The Refresh button was enhanced to clear any old information (for example, changing IP
address). In addition, the TRIOS connection dialog was also changed to refresh the instrument list when
selecting Browse.
Online Help: The online help system was upgraded to allow support of other HTML browsers other than
Internet Explorer.

of 83
DSC Instrument Control
Procedures Templates: New standard procedure templates were added for DSC to facilitate easy
experimental setup. These templates include Standard Ramp, Standard Isothermal, Standard Cyclic,
Standard Heat/Cool/Heat, MDSC Conventional, MDSC Quasi-Isothermal, and MDSC Heat Only.

of 83
ARES-G2 Instrument Control

and axial force gap closure profiles have been added.
The current closure profile is also shown in the gap pane of the control panel.

of 83
• Sample Loading Step: A new procedure step has been added that when used in combination with the
test step allows a level of experiment automation. The step allows the stage to be moved to the loading
gap, geometry gap, or a user defined gap with a closure profile. There is an option to pause for user
interaction e.g. load sample, trim sample once the desired gap has been reached. In additional data can
be acquired during the closure, and the motor can rotate at a fixed angular velocity.
• ElectroRheology (ER) Accessory Support: Support was added for ARES-G2 ER Accessory.

of 83
Data Presentation
• User-Defined Layout Files for Graph, Spreadsheet and Document: In addition to Defaults for
Graph and Spreadsheet layouts, which are based on procedure type, TRIOS now offers user-defined
graph, spreadsheet and document layouts. This allows the user to save a user-defined layout for future
recall, allowing for greater flexibility in data presentation. There are three types of saved layouts:
• Graph: Axis variables configuration including units and resolution. The axis limits will auto-
scale based on input data unless manual scaling was applied on the saved graph layout.
• Spreadsheet: Column variable configuration, including units and resolution.
• Document: Configuration of all graph and spreadsheet layouts contained in the document,
including step overlays.
• Data Range: The Hide Data functions allow you to parse the data range. Select the desired data, then
select between either Hide Selected or Hide Unselected to remove undesired data from the display
and optimize the scaling for the desired data. Unlike rescaling, the data is “hidden” or removed from
the plot. Just select Unhide All to recall the hidden data.
File Export
• XML Export: TRIOS software now offers the ability to export data to XML (eXtensible Markup Lan-
guage) format. The XML format is a universal data format which can be perfectly adapted to the struc-
ture of the test data. The XML data format allows for seamless portability and readability of data
between third-party programs and devices. Usually, the XML file content is presented in a viewer-
friendly way based on a so-called Schema Definition (XSD-File). TRIOS offers two structure files, the
RheoML and the TA schema. The RheoML structure is designed for rotational rheometer and capillary
data. The TA structure file exports the data of all TAI instruments including Rheology and Thermal
Analysis instruments.
• PDF: Any TRIOS document can be saved to PDF formatted files. Select Print > Print to PDF to save
the desired document. To save a graph as a PDF, click Save As and select PDF.
NOTE: As user-defined layouts have the greatest utility when applied to similar
data (e.g., same procedure types), it is recommended to name the saved data file
accordingly for easier identification and selection. Once saved, this layout can be
reapplied in the future by selection from the Load function.

of 83
Calibration Document: The calibration summary page can now be printed.
• Temperature Offset Table Enhancements: The temperature offset tables were expanded to account
for various environmental control units and their configuration. If values were saved in previous
tables, they should be copied before loading software/firmware to ensure proper conversion.
• FCO Chiller Control: The controls for the controls enable/disable or switching between Chiller, Air,
or Gas source now work properly
• Axial Force Adjustment End of Test Option: When set to Inherit, this mode now uses the
appropriate Axial Force value.
• Firmware Download: The download procedure was modified to always allow the download of
support files to the instrument.
• Axial Tests: Repaired image capture rate. Previously, it was hard-coded to collect at every 1 second.

of 83
AR Series Instrument Control
• Transient data acquisition has been added to oscillation time and amplitude sweeps. If transient is
selected, you still get the correlated data during the experiment, but at the end you also get additional
steps in your data file that contain the transient data (time, torque, and displacement) sampled at
0.978 KHz. Note that the displacement is corrected by an offset to center the sinusoidal signal at zero.
The displacement is also corrected for compliance. The transient can be analyzed using the FT
Rheology analysis option.
• Step Termination: All procedure steps have optional step termination based on either limit checking
or equilibrium.
• Transient Creep: Torque zeroed at end of step.

of 83
Data Presentation and Analysis
• FT Rheology has been added as an upgradeable option for AR Rheometers. This option performs a
discrete Fourier transformation on the displacement and torque signals and extracts the fundamental
and harmonic data. The results are recast as a function of the test variable (amplitude for amplitude
sweeps, time for time sweeps, and frequency for frequency sweeps). The transient total stress, elastic,
and viscous stress can be reconstructed based on the user defined number of harmonics.
• Creep to Oscillation Conversion (Rheology): The transformation of time dependent creep into fre-
quency dependent oscillation variables (J(t) ->G'(ω), G"(ω) ) has been added. This option is available
under the Transformations options.
• TTS Enhancements: The TTS analysis functions have been updated to include the following
enhancements:
• After the data is split either by temperature or frequency, the value of the constant variable
(temperature or frequency) is now appended to the step name for easy identification.
• Mastercurve file can be deleted any time during a TTS session by selecting the mastercurve
step and clicking Delete on the drop-down menu in the File Manager.
• aT and bT replace x-shift and y-shift as variables in the shift factor spreadsheet and graph.
• 1/T has been added to the available variable list in the shift factors step.
• Stamp Point Selection Window: In addition to clicking on a point to label with its curve values, you
can select the Stamp Selected Point option, allowing selection of the desired parameters (including
time and temperature).
• Add Graph Variables to Spreadsheet: This option within the TRIOS User Options has been repaired.
• Smooth: Several smoothing techniques are now available in TRIOS (Polynomial, FFT, and Least-
Squares). The desired option is set within the TRIOS Options > Analysis page. The extent of the
smoothing interval is determined by the user defined window size (1-100: 1 - less smoothing; 100
more)
• Derivative Changes
• Derivative options were expanded to included derivative with respect to (wrt) time,
temperature, or X-axis variable.
• Several derivative techniques are now available in TRIOS (Central difference, Cubic spline,
and Least-Squares). The desired option is set within the TRIOS Options > Analysis page.
• The degree of the derivative smoothing interval is determined by a user-defined window size
(1-100: 1 - less smoothing; 100 more).
• Interactive Adjustment: If you wish to interactively change or adjust the derivative smoothing
interval, click the Adjust option before making the selection above. The Derivative Adjust
window appears, which allows you to adjust the smoothing to a desired level by either 1) mov-
ing the slider bar, or 2) entering a value while simultaneously viewing the smoothed signal and
comparing it to the original data.
• Symbol Density: The default option was changed to Fine. Users now have the option to have a symbol
for every point.
• Invert Axis Option: A new option is available on the Graph > Edit ribbon or within the axis right-
click pop-up menu to invert the displayed data.

of 83
• For Rheology data files, certain geometry fields can be edited, which results in a recalculation of the
file. For example, plate diameter, compliance, inertia.
Miscellaneous - TRIOS General
• Notifications: Enhanced printed copy to adjust for multiple line text.
• Universal Analysis Files: TRIOS can now import Thermal Advantage TGA files. In addition, files
generated with Thermal Advantage software now appear as step overlay plots, which more closely
represents how they were displayed in Universal Analysis Software.
• View > File Scalars: Fixed to display the correct information for ARES-G2, RSA-G2, and
Discovery DSC.
• Menus altered to accommodate new functionality.

of 83
Discovery DSC Instrument Support
TRIOS V2.0 includes support for the new Discovery DSC instrument.
AR Instrument Control Support
Full support for the AR-G2, AR 2000ex, and AR 15000ex Rheometers included.

of 83
Additional Hardware Support
RSA-G2 Immersion geometry support added.
General TRIOS Analysis Changes
• Analysis: This component was updated to consolidate all of the analysis parameters into a new Set-
tings window and enhanced to add new functionality. Consult the TRIOS Online Help topic Basic
Steps to Analyze Data for more information.
• Analysis Settings: This includes all of the previously-available functionality (input parameters, output
parameters, and running models windows). In addition, added new functionality for label customiza-
tion. Select the Labels options to customize the displayed analysis label. Select Appearance to
customize color and label options.
• Expanded Analysis Functions: Additional general analysis functions were added to the available list,
including Signal Maximum/Minimum, Peak Integration, Peak Height, and Curve at x and y.
• Adjust Limits: A new function was added, allowing for modification of analysis limits after perform-
ing the analysis. This function is only applicable to a collection of analysis functions. It is particularly
useful for adjusting the tangent lines used for analysis functions in order to ensure the best input limits
are used (for example, Onset). Changes to limits are viewed in real time.
• Smooth Enhancements: The smoothing process was enhanced to display a preview curve before
accepting smoothing operation.

of 83
• Shift /Rotate Functionality Added: The process of curve shifting and curve rotation was added.
Curve shifting moves all of the data points on a curve up or down by a fixed value. Curve rotation
rotates a curve around a defined pivot point. A preview curve is displayed during operation.

of 83
• Calibration procedures were consolidated into the File Manager > Calibration tab for easy access.
Note that main transducer calibrations, as well as functions to analyze the results of calibration tests
such as Phase Angle Calibration, are still found on the Instrument ribbon under Calibrations.

of 83
• The Temperature Offset Table (located within the Calibration options) was refactored to display the
measured temperature, the reference temperature, and the offset. This form also allows each table to be
separately enabled/disabled while running TRIOS and at instrument startup. The uncorrected tempera-
ture is the temperature monitored when the offset table is deactivated. The corrected temperature is the
temperature recorded when the offset table is active.
• Fixed camera initiation bug that appeared on some computer systems and fixed collection of stale
images at start of test.
• Axial force nomenclature changes.
• Several changes have been made to the Control panel test status. Oscillation Acquisition status is now
correctly displayed for the first point in a step. Steady Acquisition status is now displayed.

of 83
• Motor Control Panel buttons are now selectively enabled and disabled based on running state.
• A new ARES-G2/RSA-G2 test has been added Other-DETA/DMA, where a mechanical frequency
and strain can be commanded in addition to the standard options for DETA frequency profiles. Also,
both the standard Other-DETA and Other-DETA/DMA tests now work with Axial force control.
• Fixed problem with linear Temperature/Frequency sweeps that appeared when number of points is
used rather than increment.
• Steady-state sensing is now enabled in Creep tests.
• Fixed problem with LN2 Off at end of test option not properly disabling the Liquid Nitrogen
controller at the end of the experiment.
File Operations
• Orchestrator and Rheology Advantage files can be imported for data display.
• Expanded export functionality was added to support export of multiple steps and/or multiple files at
once from the File Manager > Export options.

of 83
• Plot Header: New option to display fixed parameters at the top of the graph.
• Graph legend: The legend text can be edited by double-clicking within the label.
• Graph properties: Two options are now available for customizing graph properties:
• Automatic (using schemes)
• Custom provides the ability to customize color, symbol, and line type properties by trace and by
differentiator.
• Overlay plot: Added a new option with the Graph>Edit options to easily clear an overlay plot. Also,
use this option to remove added data from a step overlay document.
• Spreadsheet: Fixed Reload Data refresh issue.
• Notifications: New function was added to allow the ability to manually add an entry (note) into the
Notifications log.

of 83
New TRIOS Application Options
• Added ability to save notifications logs (files) in XML format in addition to the standard TA format.
• Added option to close results document at end of the experiment vs. keeping the results displayed.
• Added a prompt to save analysis adjustments when the action has not been completed.

of 83
RSA G2 Instrument Support
TRIOS V1.8 includes support for the new RSA G2 instrument.
The TA Instruments RSA-G2 Dynamic Mechanical Analyzer tests the dynamic mechanical properties of
solid materials by using a servo drive linear actuator to mechanically impose an oscillatory deformation, or
strain, upon the material being tested.
AR Instrument Control Support
TRIOS V1.8 includes beta instrument control support for AR-G2, AR2000ex, and AR 1500ex
Rheometers.

of 83
General TRIOS Changes
File Manager Changes
The File Manager is a central component of the TRIOS software. It manages displays of the experiment
sequence and results documents, as well as other components specific to the instrument type, such as
calibration and geometry manager. A navigation pane is used to switch between these options.
The view buttons at the bottom of the File Manager navigation pane correspond to different views, such
as Experiment, Results, and Geometry. Depending on the chosen view, the File Manager displays a
different set of panes, lists, toolbar, and information. The contents of the navigation pane change

of 83
depending on the connected instrument type (if online). Each view displays information pertaining to that
view and options for accomplishing tasks within that view.
• Experiments
• Set up new experiments (run sequences).
• Open stored experiment files.
• Start experiments.
• Save experiment files (no data).
• Results
• Open and Display data from TRIOS data files.
• Save and Close open data files.
• Create overlay plots.
• Create a new experiment using the procedure from an open file.
• Export data options.
• Geometry
• Displays list of configured geometries.
• Configure new geometries.
• Display parameters for the selected geometry.
• Calibrate the current geometry.
• Delete geometries.

of 83
Real-Time and Control Panel Consolidation
The Control panel is a central component of the TRIOS Instrument Control Software. To access the
Control panel, click the Home tab > Experiment toolbar > Controls .

of 83
Sections of the Control panel change depending on the state of the instrument – Idle or Running.
• The Idle state enables control over the various functions of the rheometer (Motor, Gap, Environmen-
tal, etc.) used during experiment setup, and the real-time variables display the results of your selec-
tions. The navigation pane and navigation bar are used to switch between these function controls.
• In the Running state, the function controls are replaced with point data. The type of procedure step
being run determines the point data options available. Again, a navigation pane and navigation bar are
used to switch between these options.
Hardware Accessory Support
DETA Accessory: Support for the new Dielectric Thermal Analysis (DETA) Accessory for both the
ARES-G2 and RSA-G2 has been added.
UV Accessory: Support for the UV Curing Accessory for the ARES-G2 Rheometer has been added.
ARES G2 Instrument Control
• Expanded procedure options: Three new procedure types were added.
• Temperature Ramp – IsoStrain
The IsoStrain test is designed to follow the changes in stress or force under changing or constant
environmental conditions over a selected period of time after applying a constant deformation.

of 83
• Temperature Ramp – IsoForce
The IsoForce test is designed to follow the deformation of the sample over a selected time period
under constant load (in tension or compression) and during changing or constant environmental
conditions.
• Cycle Sweep (Fatigue)
In an oscillation cycle sweep, the sample is continuously loaded/unloaded with a cyclic
deformation for a selected number of cycles.

of 83
FT Rheology and Non-Linear Analysis Option
The FT-Rheology option in TRIOS incorporates a complete software package to analyze and present the
non-linear oscillation response to a mechanical perturbation. The FT-Rheology package provides the
following features:
• Transformation of the temporal strain and stress functions to the power and phase spectrum. The initial
data set has to be generated using a transient sine strain test or any oscillation test in transient acquisi-
tion mode. The transformed functions are the strain and stress magnitude and phase.
• Extraction of the fundamental and harmonic frequencies. Calculation of the intensity ratio In/1 and the
phase ϕn, the Fourier coefficients (G'n, G"n) and the Chebyshev polynomial coefficients (en, vn), for the
selected harmonic number n. Typical non-linear measures such as: S, T, Q, G'L,G'M, η'L, η'M,… are
extracted as scalars.
• Recast the fundamental and harmonic data as a function of the oscillation test parameters ω, γ, t, and T
for plotting and further evaluation purposes.
• Reconstruct temporal strain and stress for one oscillation cycle from the odd Fourier coefficients.
The FT Rheology option consists of four transformations, and at each transformation a complete new data
file is generated. Like any other transformation, the FT-Rheology transformations can be invoked from the
File Manager or from the FT-Rheology menu on the ribbon.
NOTE: The FT Rheology and Non-Linear Analysis software is an optional package and a separate key is
required. Without this key, this option cannot be used.
Molecular Weight Distribution (MWD) Analysis Option
This function is designed to calculate the Molecular Weight (Mw) and Molecular Weight Distribution
(MWD) of a material from dynamic mechanical frequency sweep data (G'[ω] and G"[ω]) by synthesizing a
distribution based on material properties and an estimate for Mw and MWD. Dynamic data are then
calculated from this distribution and overlaid with the experimental data to determine how closely the two
sets of data agree with one other. The synthetic distribution can consist of between 1 and 10 separate
components of the same material, each with its own Mw and MWD value. This allows for very
complicated, asymmetric distributions to be synthesized, to better model the chemistry of real-world
materials. This function can also be used to calculate dynamic frequency sweep data, without starting from
a reference set of data, and based only on a given Mw, MWD, and material parameters.
NOTE: The MWD software is an optional package and a separate key is required. Without this key, this
option cannot be used.

of 83
• Procedure changes
• Transducer handling has been revamped. The Conditioning > Transducer step has expanded
flexibility to Maintain current selections (set via the control panel) or Override (set) the options
manually. This includes new settings for transducer mode selection.

of 83
• New Data acquisition option – Iterative Strain Adjustment
Use this feature to compensate for system compliance, which can reduce the measured sample
deformation (strain) considerably under certain conditions relative to the applied deformation. If
the effective strain is outside of the range defined by the tolerance, the motor strain amplitude is
adjusted accordingly, assuming constant sample stiffness. The adjustment continues until the mea-
sured strain is within the given tolerance of the commanded strain, or the maximum number of
attempts to adjust the strain is obtained.
• New Advanced test option – Maintain Axial Force during Acquisition
Option enable axial force control during oscillation data acquisition. This is particularly useful
when high rate data acquisition is required, such as in UV Curing.
• Enhanced Axial Force Control.

of 83
• Enhancements to Steady state sensing algorithm and test parameters.
• Multiwave step: Expanded environmental control to add support for temperature step
programming.
• Gap measurements during transient tests no longer produce stair-stepped output. (Improved high-
speed gap measurement.)
• Changed behavior of transducer overloads during an experiment. Tests will now be aborted if a
normal-force overload results in the stepper controller needing to move the transducer to protect it.
• Fixed Hencky strain for linear extension tests.
• Fast Sampling: Improved data collection rates are now available; see online Help for more details.
Waveforms can no longer be stored when fast sampling is enabled. They can be viewed real-time.
• Delta L signal was added to transient data records.
• Fixed equation parsing error in Arbitrary Wave tests.
• Modifications to instrument firmware download process; see TRIOS Installation Instructions and/
or TRIOS Help.
• Added support for DIN concentric cylinder geometries.

of 83
• Go to Gap button from ARES-G2 touch screen now waits for material to relax before accepting
another input.
• Instrument Configuration panel moved to TRIOS Options.
• Consolidation/changes: The instrument options, including stage control, temperature control, test
start, end of test, gap and material properties (fluid density and expansion coefficient) have be con-
solidated and added to the TRIOS Options.
• New ARES Material Properties options gap options; added feature to ARES options to prompt
when actual gap differs from geometry gap value at start of experiment.
• Revised touch-screen calibration defaults and checking, to prevent invalid calibration.
• Fixed PRT/Peltier Plate mismatch error.
• Support for temperature offset table added.
• Stress correction for parallel plate (Rabinowitch correction) – transformation to new file.
• Point Calculation: Extrapolation / interpolation for specific x values after analysis.
• TTS master curve WLF / Arrhenius (density correction).
• Fixed error generated when shear stress displayed on plot, upon selection of Williamson, Sisko, Cross,
or Carreau models.
• Analysis Force to Fit: Once the data is fit to an analysis model, the Force to Fit icon becomes active.
Click this icon to re-calculate your data points so that they sit on the analysis line calculated from your
original data.
• FFT Smoothing Options: Within the Analysis > Smooth options, new FFT data smoothing options
have been added.

of 83
• 1st and 2nd Derivatives: New functionality added to the Graph > Edit options.
• Iterative Fluid Inertia Correction: New functionality added to the Analysis > Transform options.
• Enhanced Export Options
• New export function to enable export of multiple steps/files as once; also option to send to Excel
directly.
• Export spreadsheet data to CSV now includes limits.

of 83
ARES-G2 / RSA-G2 Feature Enhancements
• Torsion Geometry: New Geometry setup corrected to display all the size parameters at startup.
• EVF/SER: Added missing Extensional Strain variable.
• Procedures
• Creep: Corrected missing Steady state sensing parameters for ARES-G2 procedure.
• Conditioning > UV: Corrected UV Intensity setting.
• Improved correlation results when 3 or less correlation half cycles are specified.
• Improved calculation of creep pretest parameters (motor PIDs).
• Corrected display of saved ARES-G2 and RSA-G2 procedure parameters to remove non-
instrument specific (ARES-G2 vs. RSA-G2) parameters
• Tool Expansion Calibration enhanced to set transducer to high range and spring mode to avoid
potential overload conditions.
• Added ARES-G2 support for the APS temperature control system.
• Fixed hencky strain for linear extension tests.
• Fixed equation parsing error in Arbitrary Wave tests.
• Gap measurements during transient tests no longer produce stair-stepped output. (Improved high-
speed Gap measurement.)
• Revised touch-screen calibration defaults and checking to prevent invalid calibration.
• Fixed PRT/Peltier Plate mismatch error.
• Corrected DIN concentric cylinder geometry constants.
• Fixed error generated when shear stress displayed on plot, upon selection of Williamson, Sisko, Cross,
or Carreau models.

of 83
• Axial Force Enhancements
• Algorithm changes for faster tracking.
• New Priority option: Axial Force adjustments only occur between data point acquisition. In the
previous version of TRIOS, data sampling was given priority over Axial Force adjustment. In
other words, if the Axial force adjustment could not get the measured axial force to be within the
Axial Force window (set point plus or minus sensitivity) during the idle time between measure-
ments, the acquisition could proceed regardless of the actual axial force. New Priority option now
allows user to give priority to either Data Sampling (acquire data regardless of actual axial force)
or Axial Force (continue adjusting axial force until the measured force is within the AutoTension
window).
• Removed Hold Current Force option from Gap Control panel: To hold a force on a sample after
loading, enter values in Axial Force and Sensitivity then check the Set Initial Value box.
• Inherit option has been added to the Axial force mode option within the Conditioning > Options.
Use this when you desire for the current axial force and other parameters applied to the sample to
be inherited based on the last setting (either from the Gap Control panel or previous Condition-
ing > Options step).

of 83
• Advanced Testing Options
• Parallel Superposition, ability to superimpose steady shear rate on oscillation experiment, added
to the Advanced options of oscillation tests.
• Normal Force Transducer Mode Selection, available under the Advanced options for all test
steps (oscillation, flow, step, and other).
• Transient data collection option added to oscillation mode, available under the Data Acquisition
section for Oscillation tests: Allows collection of uncorrelated data: Torque, Displacement and
Normal Force of the selected Oscillation test type. Data can be later exported for user analysis.
Standard correlated material parameters: G', G'', * etc., are not calculated and stored in this option.
Data acquired in this mode are similar to those generated in the Transient Sine Strain test, and are
reported that way in TRIOS.
Note: Axial Force Control is not recommended with FRT normal force transducer
mode selected.

of 83
• Multiwave test support including waveform preview.
• Additional harmonics have been added (10th through 256th) as well as the ability to specify a
phase offset for each harmonic.
• Multiwave data can also be acquired using transient (non-correlated) mode, as discussed above.

of 83
• Arbitrary Wave test support including waveform preview. The Arbitrary Wave test allows the defini-
tion of the strain history used to deform the sample by supplying one or more equations for strain as a
function of time. Up to four individual equations, each with a specified duration, can be used in each
step, and multiple steps can be used in experiments.

of 83
• Transducer Zero Timing
• In previous version of TRIOS, the time required to zero a transducer channel was fixed, which
resulted in typical startup delays of about 45 seconds between the start of experiments and the start
of data acquisition. This has been streamlined to typically take less than 10 seconds to complete.
Additionally, this behavior can be overridden in a Transducer Conditioning block to either com-
pletely disable transducer zeroing, or use 3 different zeroing times. The default mode is 4 seconds
(Fast + Autorange).
Approximate Transducer Zero Times (Seconds)
Mode Single Transducer
All three Transducers /
(Autorange ON)
Fast 2 4
Standard 7 10
Precision 23 64

• Geometry Enhancements
• Geometry selection is now part of the Home Ribbon options for increased visibility and ease of
selection. It is no longer possible change the selected geometry within the Geometry bar selection
of the test setup or from the Geometry Manager. Parameters of selected geometry are editable
within the Geometry block.
• Geometry constants have been modified to include input of upper and lower geometry compliance
values separately.
• The compliance and inertia have fixed SI units as follows: Compliance [mrad/N.m];
Inertia [µN.m.s2
]
• Temperature gap compensation parameters for active and passive control have been moved from
Conditioning > Options step to geometry section. Note that gap compensation is automatically
disabled when Axial force control is running.
Note: All current geometry files will be deleted upon installation of this new
version of TRIOS software and therefore will require new setup. Before installing
this new version, record the parameters of your current geometries for reference.
Setup is slightly different. See attached documentation for further details.

of 83
• Added support for the following geometries: SER2 universal testing geometry, torsion cylindrical,
concentric cylinder geometry types.

of 83
• Real Time Variable Pane
• Enhanced to separate real time (updated several times a second regardless of whether a test is
running) and last point variables (which are updated only after a data point has been processed).

• Data Manipulation
• Smoothing
• Merge Steps
• Split Steps

of 83
• Point Display (Waveform) Enhancements
• The data shown in the point display of an oscillation experiment should not be cross-correlated to
calculate material functions (such as G’, G”, η* …). It is intended as a diagnostic tool to evaluate
the quality of the signals. The table view for point display has been removed. If cross correlation is
desired, a new option in the Data Acquisition section of Oscillation experiments has been added
[Transient data collection] to collect transient data for user analysis. See “Advanced Testing
Options” on page 70 for additional information.
• Support for Lissajous Plots in Oscillation mode.
• Support for Point Display for Flow Sweep.

of 83
• New Experiment setup has been improved.
• There are now two new Experiment options: Copy Last and Default. Copy Last creates a new
experiment setup based on the last run experiment (copying the sample and procedure informa-
tion). Default creates a new experiment with no (empty) sample information and a single step pro-
cedure. In both cases, geometry is based on selected option as specified above.
• Only one new experiment can be setup and viewed at a time. If a new (unrun) experiment is
already loaded and Copy Last or Default (Experiment) is selected, you will be prompted to
replace the current setup.
• The START button is enabled only when viewing this new experiment document (not when view-
ing a saved data file or other type of document).
• Within new experiment setup, only one section can be opened at the time. If one section is
expanded (opened), the previous open section will automatically collapse. To view more than one
section at a time, hold down the shift key while clicking on the section bar.
• Expanded file name tokens to include Project and Date.
• Repaired run execution error resulting from back to back Sine Strain tests.
• Steady stress option removed from Motor Control panel.
• ARES-G2 FCO feature for LN2 to Air switching and LN2 to Gas switching has been repaired.
• Stress control enhancements including expanded environmental control support, offset correction
between selecting between Run/Calculate and Load PIDs within the Conditioning > Stress Control
step; refinement of low viscosity criteria when calculating PID constants.
• Image Collection Enhancements
• Image capture has been changed from a global run parameter to a step based option. As a result,
this option has been moved from the Image panel to the experimental setup for each test step
under Data Acquisition options.
• Camera images are now stored as JPEG vs. BMP with the experimental file, reducing overall file
size

of 83
• Added image capture interval rate for time based tests, such as Oscillation time sweep, Stress
Growth and Oscillation Temperature Ramp tests.
• Non time-based tests (such as Frequency Sweep, Amplitude Sweep, Temperature Sweep and Flow
Sweep) will have an image stored with every data point generated. Images are updated and stored
at a maximum rate of approximately once per second. Note that at faster data rates images may not
be acquired and attached to data points.
• Images can now be exported from the TRIOS file to various file format options.
• By default, the Normal Force transducer will be set to Spring mode at the end of the test.
• Previously, the motor would continue to oscillate during soak time between oscillation measurements
in certain cases. The motor is now stopped in all cases.
• Enhanced data handling communication for long and fast collection experiments.
• When an instrument safety system aborts a test, Event messages have been added to indicate the reason
that the Abort was generated.
• Fast-Correlate measurements are no longer limited to 65536 points per measurement zone.
• Fixed an issue where the motor would spin slowly after the instrument was left idle for extended
periods of time.
• RAD File Export (for import into Orchestrator software) enhanced to properly associate data types for
exported variables.
• Transducer range now properly represented in graph when range changes during an experiment.
• Enhanced the TRIOS application performance when opening and closing large data files.
• TRIOS software version and run date captured within data file in the Procedure summary.
• Units and tick mark preferences are now saved as part of graph representation preferences.
• Text color can now be selected from the Ribbon/Format options using the mouse selection vs. using
the Enter key.
• Graph Legend has been enhanced to link selection with curve selection on the graph.

of 83
• The Views menu to select between open tabs (views) within a document has been fully implemented.
• Start, Stop, Copy Last Experiment, and Default Experiment were added to the quick access bar for
easy access.
• Added new function To New Overlay Document within the View menu to facilitate creation of a new
overlay document based on selected view.
• File manager now has its own mini-ribbon for quick access to file manager functionality.
• Rescaling Enhancements including:
• When entering manual rescale limits, the tick interval will be automatically optimized, if not spec-
ified.
• The axis labeling will automatically switch to scientific notation when the data exceeds 107
or
greater.
• Scientific axis tick labeling has been changed to 10x notation vs. Ex notation on the graph.
• After changing units, scaling is properly adjusted.
• Fixed crash when the graph got too small.
• Analysis Enhancements including:
• Analysis parameters can now be adjusted after the fit is complete to investigate effect on quality of
fit. Parameters may be copied to the input parameter window to be used for next fit.
• Frequency-cycle oscillation steps can now be split into temperature sweeps as well as frequency
Sweeps through the File Manager > Transformations options.
