Operating Procedure
3. Operating Procedure (continued from previous page)
●Zero adjustment
To conduct zero adjustment, press the AIRADJ. switch for approximately three seconds. The buzzer
will then beep once, followed by two beeps after a short pause. If zero adjustment fails, the buzzer
will beep once followed by continuous beeps. This means that a gas in the air is affecting the Gas
Detector. In that case, conduct zero adjustment in clean air. The sensor may not operate stably,
depending on the environment, or if the Gas Detector has not been used for a long time. If that
is the case, the gas concentration value will flash. If the value flashes, be sure to conduct zero
adjustment, or the precise measurement of gas may not be possible.
●Range
To change the bar graph range, press the POWER switch while the gas concentration screen is
displayed. The range will be set to AUTO by default when the Gas Detector is turned ON. Each time
the POWER switch is pressed, the display will show the next range in the order of H, L, and AUTO.
〈AUTO range〉
When gas is detected, the digital numeric value and the bar graph level will increase
simultaneously.
If the bar graph level exceeds the full scale, the range will change from L to H automatically and
the scale of the bar graph will change. Furthermore, if the gas concentration drops, the range will
automatically return to L.

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, OL will be displayed.
High-concentration gas may have an adverse influence on the sensor. Promptly introduce cleaned
air into the Gas Detector. Turn OFF the Gas Detector after confirming that the gas concentration
falls and the Gas Detector is free of gas.
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 gas concentration drops in a
clean air.
