Connecting The Gas Compartment; Pumping Back In The Measured Gas Compartment; Pumping Back In External Gas Compartment (Pressurised) - WIKA GA11 Mode D'emploi

5. Commissioning, operation
If the instrument is not connected to the mains in time, it will shut down automatically in
order to prevent damages and data loss. In the mains operation, the battery is charged and
the instrument can be switched on again at the same time and operate without restrictions.
Establishing connection to mains supply
1. Connect power supply unit to the power cord.
2. Connect power supply unit to mains connection on the operating panel.
3. Connect the power cord to the socket.
⇒
Connection to mains supply is established.

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 model GIR-10)
For an optimal measuring result evacuate the connetcing hose prior to measurement.
To perform a measurement, the pressure of the gas compartment to be measured has
to 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.
5.2.1

Pumping back in the measured gas compartment

▶
Connect "Inlet, return pumps " to the gas compartment.
⇒
Gas compartment is connected.
During pumping back, the gas is pumped back into the gas compartment via the "Inlet,
return pumps ".
5.2.2

Pumping back in external gas compartment (pressurised)

Requirement:
The filling pressure of the external gas compartment is between 1.3 ... 10 bar abs.
(SF₆-Q-Analyser)
The filling pressure of the external gas compartment is between 1.3 ... 12 bar abs.
(g³-Q-Analyser)
1. Connect "Inlet, return pumps " to the gas compartment to be measured.
2. Connect "Outlet for gas cylinder " to the external gas compartment.
⇒
Gas compartment is connected.
