5.2 Connecting the gas compartment

CAUTION!
Escaping gas results in environmental hazards
If there are leakages at the connecting elements, the environmentally
hazardous gas may be released to the atmosphere.
▶
Make sure that there is no leakage at any connections (e.g. by using gas
detector GIR-10)
For an optimal measuring result, evacuate the connecting hose before the measurement.
To perform a measurement, the pressure of the gas compartment to be measured must
be at least 1.3 bar abs.. If the inlet pressure is below 1.3 bar abs., it is possible to use an
inlet pressure control unit (e.g. model GA05) to raise the pressure.
