Preparing for measurement
Use the flue gas probe for the draught measurement. The
draught measurement can be conducted before or after a
flue gas measurement.
A draught measurement is only possible with the pump
switched off. The + pressure inlet of the device must be
open!
Do not change between battery and mains operation
during the draught measurement (voltage fluctuations
influence the result of the measurement)!
If you conduct the draught measurement after a flue gas
measurement, a head of pressure exists in the hose after
the pump has stopped, which must be dispelled. This
occurs within approx. 30 seconds.
Remove any traces of condensation in the flue gas probe
(shake out the probe with the tip towards the floor).
