8.7.4 Setting Purging
Purging is to remove condensed water in the calibration gas pipe by supplying a span
calibration gas for a given length of time before warm-up of the detector. This prevents
cell breakage during calibration due to condensed water in the pipe.
Open the solenoid valve for the automatic calibration span gas during purging and after
the purge time has elapsed, close the valve to start warm-up.
Purging is enabled when the cell temperature is 100
Њ C or below upon power up and the
purge time is set in the range of 1 to 60 minutes.
