6.7.3 Air purge pressure
If a pressure gauge is installed on air purge pipe, and connected to the control unit, the analyzer can emit an
alarm when the purge pressure is below the setpoint.
● Be sure to install a pressure gauge if the purge pressure is unstable.
● If you measure high-temperature gas without purging the analyzer, the analyzer may get damaged.
When there is no sensor to be connected, set the air purge pressure to "No". If you select "CH1" or "CH2"
while there is no signal input, the analyzer emits an "analog signal error" alarm.
