Calibration set-up
Warning
Do NOT attach the gas supply to the gas analyser before
putting the analyser into the ‘Gas Check’ screen. Select
‘Check Spans’ from the ‘Operation Settings’ menu.
The regulator supplied with the calibration kit has been configured to deliver a fixed flow.
As the regulator’s flow is factory set, it only requires a few turns to open, no adjustment
is necessary.
Warning
Exhaust port
When the gas analyser is being calibrated, there are two
possible exits for the gas, via the usual manner out of the
exhaust (yellow) port of the analyser or in cases of over-
pressurisation the 1/16
”
port on the red pressure relief valve
located on the regulator.
It is recommended that both ports have exhaust tubing
attached.
The exhaust tubing must emerge in a well-ventilated area.
Ensure there are no leaks in the tubing and connections.
The calibration of the gas analyser should be carried out in a
safe area with all necessary precautions taken when using
potentially dangerous, explosive or toxic gases.
Note:
There is also potential for gas to expel from the internal flow (blue) port of the
gas analyser (applies to the GA5000 only).
