1.3 Important Handling Cautions and Warnings

DO NOT let the force gauge fall or
drop onto the ground!

DO NOT pass or handle liquids
near the force gauge to prevent
spillage and liquid damage!

Never use the forge gauge if there is
an object or material wedged
between the measuring rod and
frame!
Always line up the measuring rod
parallel to the object being
measured to prevent the rod from
warping and damaging the device!

DO NOT attempt to measure the
force of an object that is submerged
in a liquid!

-3-


1.4 Safety Rules for Measurements over 1kN (about 100kg)
Warnings:
 Exceeding the range of the force gauge by more than 20% may cause damage to the sensor and endanger
the user.
 The bearings should always be attached to the external load cell during measurements to prevent
damage to the unit and injury to the user.
Proper Set-up:
Measurements with an external load cell should be done under proper supervision.
1. Attach the bearings into the external load cell by screwing them into the parallel holes on each side.

2. Connect the wire to the force gauge.
3. Put the load cell on a flat surface and turn the force gauge on.
4. Once the device has initialized, connect a load to the bearings to perform a measurement.
*Make sure the force gauge meter is secure so it does not fall or get pulled during measurements.

Maintenance, Inspection, and Repairs:
 All maintenance and repairs on the force gauge and external load cell should only be conducted by
trained professionals.
* Force gauges with a capacity of 1kN or above are equipped with an external load cell connected by a
wire. Bearings are connected to the load cell to prevent excess stress when mounting a load. The meter
and load cell are delivered in two separate cases.

Chapter 6: Mounting Force Gauge on a Test Stand
One of the unique capabilities of the FA Series force gauge is its ability to be mounted on a test stand.
The test stand is dual guiding cylinders with a 3mm pitch lead screw. Attached to the mounting bracket for the
scale are electronic calipers. The caliper reads to 8in (200mm). The calipers read in inches or millimeters
(push button select). It can be zeroed at any location on the caliper scale. Inches read to .001 and millimeters
read to .01.
1. The device has four screw holes on the back of its frame, which align with the mounting holes on the
test stand. Use the screws included with the test stand to mount the device to the stand.
* When using the test stand, make sure the device is secure, but do not over-tighten the screws as this
may damage the unit.

2. Once the force gauge is mounted connect a desired attachment.
3. If desired, other attachments can be connected to the base of the test stand.
4. To measure forces turn the knob on the test stand clockwise to raise the unit up and counterclockwise to
lower the unit down.
Note: The test stand’s knob moves the gauge 3mm, up or down, per full turn or rotation.
- 12 -


Chapter 7: Getting Started
1. Carefully take the force gauge out of the case.
2. Force Gauges with an external sensor require the bearings to be screwed into the load cell for support.
Note: If using the unit on a test stand refer to the chapter: Mounting the Force Gauge on a Test Stand.
3. Select a suitable tip in order to effectively conduct a measurement. (Choose the tip that will best
measure the force of the object being tested).
4. Slowly screw the tip onto the measuring rod at the top of the force gauge.
5. If necessary, connect the force gauge to a power outlet by plugging the AC Adapter into the 12V socket
at the bottom of the unit. Once the AC adapter is connected to the force gauge, plug the other end into a
wall socket.

Chapter 13: Taking a Measurement
The FA Series force gauges are designed for measuring the compressive/tension force in laboratory,
manufacturing, and quality control applications.
Measurements up to 200N can be performed by holding the force gauge in your hand.
For measurements above 200N it is strongly recommended that a double-hand handle is attached to the force
gauge (additional equipment).
The USB port allows for all measurement results to be loaded onto a computer for further analysis and
recordings.
After configuring the force gauge, take measurements by using the steps below:
1. Attach a tip suitable for the measurement about to be performed (i.e. pull, push, mass).
2. Turn the device on in the starting position (tare the device if necessary).
Note: If the device needs to be mounted to a test stand or has an external load cell, secure the device
for measuring.
3. If the intended measurements are to find out the push/pull peak force, the PEAK button should be
pressed to initialize the feature (press once for push peak, twice for pull peak).
Note: The force gauge with external load cell requires the PEAK button
be pushed once for pull force and twice for push force (opposite of the
internal force gauge).

13.1 Compressive Force (Push)

4.

To measure the push force of an object, angle the device so it is linear to the object.
If measuring by hand grasp the device firmly.
Push the force gauge forward with the attached tip pressing into the object.
Study the measurements being recorded as the force is applied.

13.2 Tension Force (Pull)
1.
2.
3.
4.

To measure the pull force of an object, angle the device so it is liner to the object.
If measuring by hand grasp the device firmly.
Wrap the hook tip around the object and pull the force gauge away from the object.
Study the measurements being recorded as the force is applied.

* Do not exceed the gauges maximum capacity by more than 20%
All stored data can be viewed in STATS (Applications > Data Stored > Stats). From here you can view the
data in a histogram or chart. Stored data can also be saved to a computer for analyzing or printing.
* When you are packing the force gauge up, make sure to remove any attachments from the measuring
rod to prevent damage.

Chapter 14: Calibration
Calibration is an important step when weighing the mass of an object. This process is used to adjust the force
gauge or scale to the actual gravity and barometric conditions of the user’s current location. It also accounts for
any drift due to temperature changes. To get to this function go to the Main Menu.
There are multiple methods that can be used to calibrate the gauge:

- Use an object of known weight to correctly adjust the scale.

1. Position the device upside down with the hook tip
attached. The gauge should be secured in the same
fashion that you plan to use it to weigh objects in (e.g.
locked into a stand, by hand, etc.).
2. Set the Mode to Mass
3. Select the Load weight exactly equal to the weight of
the calibration weight that will be used to calibrate.
4. Place the calibration weight on the hook or hook-held
platform.
5. Select Calibration – START to initiate calibration.

- Input the g-value (gravitational acceleration) of the location where the force gauge is
being used.
For this method, the exact g-value must be known and can be typed in using the arrow keys.
Note: The g-value of a given location can be found on the internet. (e.g. Wikipedia, a municipality site, etc.)

- Input the Geographical Location of where the force gauge is being used.
If the g-value is not known, the geographical coordinates can be entered.
1. Select Geographic Location
2. Enter the Latitude of the current location
3. Enter the Elevation of the current location
By entering these coordinates, the g-value will automatically be updated therefore calibrating the device.
Note: The geographical coordinates of a given location can be found through multiple methods including:
A GPS, Smart Phone Apps, and the Internet.

- Input a Correctional Value
Errors may occur through extensive use and overloading of the force gauge. To account for these errors a
correctional value must be entered to adjust the force gauge.
Note: In order to perform a Correction an object with a known weight must be obtained.
1. Position the device upside down with the hook tip attached. The gauge should be secured in the same
fashion that you plan to use it to weigh objects in (e.g. locked into a stand, by hand, etc.).
2. Place the calibration weight on the hook or hook-held platform.
3. Find the difference between the actual weight and the measured weight of the object.
Note: The scale must be set to a unit of weight for this operation.
4. Select Correction and enter the difference.
By entering this value the force gauge will automatically be adjusted by calibrating itself.

* Factory calibration can be used to reset the force gauge to its default settings from its original
calibration at the manufacturer.

Chapter 15: Maintenance, Trouble Shooting, and Repairing Minor
Damage
There are a number of errors caused by the user that will cause the force gauge to not work properly.
1. The force gauge should always be kept clean.
 If dirt or dust builds up and gets in any of the opening of the force gauge, the software can begin

to malfunction.
2. Make sure no substances get stuck between the measuring rod and the frame of the device.



If anything gets wedged in this area, it can cause the measurements to become inaccurate and can
lead to permanent damage of the unit.

* If anything substances do get wedged inside, they should be removed using a tool which does not
conduct electricity.
3. Unauthorized personnel should not perform any repairs on the force gauge.
 If anyone other than a trained technician tries to repair or adjust the force gauge, they can cause
permanent damage.
Error Indications:
