9. Pressure measurements

9.1 Connection diagram

Connect the metering point with the pressure inlet P+ on the measuring
device using the burner pressure hose for pressure measurements up
to a max. of 160 mbar (gas, nozzle or kinetic pressure).

9.2 Pressure measurement

Selectable functions are:
Null: The displayed value is set to zero
>> / <<: Switching between statistics and chart
Start: Starts the pressure measurement
Cancel: Cancels the pressure measurement
Press the Start button, to start; after the required time period, stop the
measurement with Stop. After the pressure measurement is started,
the current pressure, the starting pressure, the difference to the starting
pressure and the previous duration of the measurement are shown. The
final pressure is shown when the measurement is stopped. The arrow
key >> can be used during the measurement, to switch to the diagram
view. After completing the pressure measurement, the result is dis-
played.

9.3 Tightness test

Test pressure, stabilization time and measurement time can be set for the general tightness
test.
This function also allows conducting tightness tests for gas pipes, liquid gas pipes and drink-
ing water installations.
Work on gas pipes requires precise knowledge and adherence to the respective
standards and worksheets of your country-specific applicable legal regulations!
Limit the test pressure to the metering range of the pressure sensor used. Higher
pressures destroy the pressure sensor.
