> Replace the sensor
6.1.6. | Instrument settings | Sensor protection
Threshold values can be set to protect the CO/NO sensors against
overload. The sensor protection is activated if the threshold is
exceeded:
• Fresh air dilution if exceeded
• Shutdown if exceeded again
When dilution is activated, the CO and CO undiluted values are
displayed in a blue font. On the printout, a “*” is shown after the name
of both values to indicate dilution.
To disable sensor protection the threshold values must be set to
0 ppm.

Extremely low absolute pressure causes wrong calculation of the
O2sensor service life. Therefore, when the measuring instrument is
used at great heights, the factory set value should be adjusted so
that an O2sensor is not displayed prematurely as “expended”.
If using the measuring instrument at heights up to approx. 1800 m
above mean sea level (MSL), the factory setting (922 hPa, equals
approx. 800 m above MSL) can be retained.

- The measuring instrument switches off.
6.2. Measuring
6.2.1. Preparing for measurement
6.2.1.1. Checking the condensate container fill level
Regularly check the fill level of the condensate container and empty
it in good time; see Draining the condensate container, page 28.
6.2.1.2. Checking the particle filter
Regularly check the particle filter of the flue gas probe for
contamination and replace in good time; see Checking/replacing
the particle filter, page 35.
6.2.1.3. Zeroing phases
Measuring the combustion air temperature (AT)
If no combustion air temperature probe is connected, the
temperature measured by the thermocouple of the flue gas probe
during the zeroing phase is used as the combustion air
temperature. All dependent parameters are calculated using this
value. This method of measuring combustion air temperature is
sufficient for systems dependent on ambient air. However, ensure
that the flue gas probe is near the intake duct of the burner during
the zeroing phase!
If a combustion air temperature probe is connected, the combustion
air temperature is measured continuously via this probe.

6 Using the product
19
Gas zeroing
The gas sensors are automatically zeroed when the instrument is
switched on.
> To manually start zeroing of the gas sensors: | Zeroing Gas
Sensors.
Draught/pressure zeroing
The pressure sensors are continuously zeroed.
The flue gas probe can be in the flue gas duct during the zeroing
phase, if there is no overpressure in the duct and a separate AT
probe is plugged in. The minus connection for differential pressure
measurements must be clear (ambient pressure, not closed).
6.2.1.4. Performing a gas path check
Regularly check the measurement system (measuring instrument
+ flue gas probe) for leaks.
A high O2value, in particular, may be an indicator of a leaking
measurement system.
> | Gas path check.
6.2.1.5. Installing the probe mount testofix®
