Action
3. Measure the pressure difference at the ring
pipe with the differential-pressure meter.
Meter ranges: 0..5hPa
Enter the reading in the service log in the
column “
 p2 [hPa]“.
4. Meaure the pressure difference between the
flow cell and the atmosphere.
Enter the reading in the service log in the
column “
 p3 [hPa]“.
Because this reading depends heavily on
the pressure in the off gas duct, it can
fluctuate widely!
5. Using the gas flowmeter, measure the purge
air flow q1 between the purge air blower and
the purge air filter.
Enter the readings in the service log in the
column “q1 [l/min]“.
If the measurements are out of line,
continue with Sections 5.4/ 5.6 and then
repeat the measurements!
6. Switch on the installation in the normal
operating mode by simultaneously pressing
keys
 +  .
If the measured values vary from the values in the service log ("Start-up,
corrected readings") by more than 25%, the installation requires servicing.
