8.7.3.3 Default Values
When the analyzer is delivered, or if data are initialized, parameter settings are by default, as shown in
Table 8.18.

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°C or below upon power up and the purge time is
set in the range of 1 to 60 minutes.
