Zeroing takes place automatically when the CxHy sensor is
activated. To ensure that accurate CxHy readings are obtained,
you should then wait about 10min (with the instrument switched on)
before starting another zeroing process manually.
To prevent the CxHy sensor from drifting during lengthy
measurement operations, zeroing should be carried out from time
to time.
6.2.2. Using the flue gas probe
Removing plastic cap
> Before starting a measurement, remove the plastic cap fitted on
the flue gas probe and set it aside. The plastic cap is required for
the gas path check (see Section 5.5.2).
Checking the thermocouple
> Make sure that the thermocouple of the flue gas probe does not
touch the probe basket. Bend the thermocouple back if
necessary.
Aligning the flue gas probe
> Turn the probe to align the thermocouple so that it is freely
exposed to the flue gas flow.
> Align the flue gas probe in the flue gas duct so that the tip is in
the hot spot (area of the highest flue gas temperature).
6.2.3. Applications
You can choose from fixed saved and a user defined application
(application defined on the basis of the measuring object).
The memory contains suitable device settings for the meas. box
and typical fuels and calculations for these applications. These
quickly provides you with optimized device configurations for the
respective measuring task and the device will automatically inform
you about important application specific peculiarities (information in
the display).
