Measuring

Preparing for measurement

The First steps chapter (see First steps, page 26) must
have been read.

Testing for leaks

The entire measurement system (probe, condensate trap, hoses
and connections) must be tested for leaks before each
measurement to avoid incorrect measurements due to the
infiltration of external air. Testing is carried out while the pump is
running and may be performed by attaching a compressed balloon
pump. The measurement system is leak-tight if the balloon pump is
not filled with air.

Zeroing phases

Measuring the combustion air temperature
If no combustion air temperature probe is connected, during the
zeroing phase, the measured temperature of the flue gas probe is
taken as the combustion air temperature.
The flue gas probe should not be in the flue gas duct during
the zeroing phase.
All dependent parameters are calculated using this value. This
method of measuring combustion air temperature is sufficient for
systems dependent on ambient air.
If a temperature probe is connected, the combustion air
temperature is measured continuously via this probe.
