Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.

Approved (see application information of the radio probe).
A radio module (accessory part) is required for the use of radio probes. The
instrument can establish a connection with a maximum of three radio probes.
Each radio probe has a probe ID (RF ID). This consists of the last 3 digits of the
serial no. and the position of the slide switch (H or L) in the radio probe.
Setting up a radio probe:
A radio module (accessory part) is inserted in the instrument.
See chapter COMMISSIONING, p. 9.
The configuration menu is open, config. is displayed.
The radio probe is switched on and the transfer rate is set to 2 readings
per second (see the advice on using the radio probe).

25. Setting the “Area” parameter/Activating shape:
Five areas can be stored for the “Area” parameter. Three shapes are defined
in the default setting (one rectangles: edge length a and b, one circle:
diameter d, any shaped area: cross-section area A). The dimensions of the
areas can be adapted in the instrument. It is possible to reassign the shapes
using the PC software (435-2/-4 only).
When K-factor activated (see chapter DEVICE, p. 13): An offset factor is stored
for each area. If parts of an area are covered (e.g. grilles on ventilation
openings), this can be calculated out using the offset factor. What must be
indicated is the free part of the area (20% covered --> 80% free area -->
offset factor 0.8).
For measurements made at outlets and volume flow regulators with defined
differential pressure measurement points, a component-specific correction
factor (k-Vol) prescribed by the manufacturer can be entered instead of the
area input.
For measurements at ventilation outlets with a funnel the parameter Funnel
must be activated. The funnel set (order no. 0563 4170) consists of a funnel
for measurements at plate outlets (200 x 200mm) and a funnel for
measurements at ventilation outlets (330 x 330mm) in combination with the

7. Measuring
This chapter describes the steps that are required to perform measurements
with the product.
Particular probes must be plugged in or switched on and registered (radio
probes) according to the variable that is to be measured.
Some probes require a warming-up phase until they are ready to measure.
For some variables additional calculation parameters have to be set if correct
measurements are to be obtained.
See PARAMETER/AREA, p. 24.
For the calculation of the U-value, please refer to the documentation included
with the U-value temperature probe (0614 1635).
Required for the calculation of the heating/cooling performance of assemblies:
· A vane probe (for determining the volume flow) must be connected.
· 2 wireless humidity probes (for determining enthalpy at the input and output
of the assembly and for calculating tightness).
· The parameter pressure (for the calculation of tightness) must be entered.
· The calculation factor enthalpy must be activated. The enthalpy is integrated
in the calculation of performance, an enthalpy value cannot be displayed..
· The wireless humidity probe allocated to radio channel 1 must be positioned
next to the vane probe, as its readings are automatically used to calculate
the mass flow.

27. When measuring ambient CO, observe:
· The ambient CO probe must be situated in fresh air (CO-free) during the
zeroing phase.
· Cigarette smoke influences the measurement by more than 50ppm. The
breathed air of a smoker influences the reading by approx. 5ppm.
· The flow impact of the gas influences the measurement accuracy. Frontal
impact on the sensor leads to higher measurement values. The best
measurement results are acheived with a slight movement of the probe back
and forth.
