Checking the particle filter

6.2.1.3.

Zeroing phases

Regularly check the fill level of the condensate container and empty
it in good time; see Draining the condensate container, page 28.
Regularly check the particle filter of the flue gas probe forcontamination and replace in good time; see Checking/replacing
the particle filter, page 35.

Measuring the combustion air temperature (AT)
If no combustion air temperature probe is connected, thetemperature 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 thisvalue. This method of measuring combustion air temperature issufficient for systems dependent on ambient air. However, ensurethat the flue gas probe is near the intake duct of the burner during
the zeroing phase!

18

6 Using the product
If a combustion air temperature probe is connected, the combustion
air temperature is measured continuously via this probe.
Gas zeroing
The gas sensors are automatically zeroed when the instrument isswitched on.
> To manually start zeroing of the gas sensors:
Sensors.

| Zeroing Gas

Draught/pressure zeroing
The pressure sensors are continuously zeroed.
The flue gas probe can be in the flue gas duct during the zeroingphase, if there is no overpressure in the duct and a separate ATprobe 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 O2 value, in particular, may be an indicator of a leaking
measurement system.

20

6 Using the product5. Insert the flue gas probe through the probe mount into the fluegas duct.
When using the testofix® probe mount, the measuring
instrument is exposed to heat radiating from the flue gas
duct during the measurement. In order to prevent
consequently affecting the combustion air temperature a ATprobe with cable must be used for the measurement!

6.2.1.6.

Using the modular flue gas probe
Checking the thermocouple

The thermocouple of the flue gas probe must not lie against theprobe cage.
> Check before use. Bend the thermocouple back if necessary.
Aligning the flue gas probe

Use distilled water, or alternatively mild solvents such as
isopropanol to clean the flue gas analyzer. If using
isopropanol, please refer to the instruction leaflet for the
product. Isopropanol fumes have a slight narcotic effect,
and typically cause irritation of the eyes and sensitive
mucous membranes. When using it, please ensure that
there is adequate ventilation.
Do not store any objects that have come into contact withsolvents and/or degreasers (e.g. isopropanol) in the case.
Evaporating or leaking solvents and/or degreasers may
cause damage to the instrument and to the sensors.
The use of strong or harsh alcohol or brake cleaner can
result in damage to the instrument.
