Gas Alarm
If the gas concentration reaches the alarm level, the gas alarm will be turned ON. When the gas
concentration drops below the alarm level, the gas alarm will be automatically turned OFF.
Only the gas alarm buzzer will stop if the BZ.STOP switch is pressed at the time of a gas alarm.
If the gas concentration reaches the alarm level again, the gas alarm buzzer will sound again.
If the pointer scales out when detecting high-concentration gas, a digital display is carried out from
25.1vol% to 50.0vol%. The Gas Detector will display OL if the concentration is 50.1vol% or higher.
Note
If the BZ.STOP switch is continuously pressed while the gas concentration
screen is displayed, the alarm point will be displayed for approximately three
seconds, and the preset alarm point can be checked.
CAUTION
To turn OFF the Gas Detector, wait until the oxygen concentration comes
back to 21 vol % in clean air.
The alarm lamp flashes.
