When a gas alarm occurs, the alarm type is
indicated on the LCD display and the corresponding
gas concentration display blinks.
Display example: Carbon monoxide (CO) concentration: 200 ppm
when the third alarm is triggered
NOTE
If the gas detection range is exceeded (over scale), [OVER] appears on the LCD display, and [∩∩∩∩] will blink
in the gas concentration display area.
WARNING
A gas alarm indicates the presence of extreme danger. The user must take appropriate action after taking
appropriate steps to ensure safety.
NOTE
The alarm pattern can be checked in the alarm setpoint display in display mode. Note, however, that the gas
concentration display will not blink in alarm tests. (Refer to ‘7-4. Performing alarm tests’ in the Technical
Manual.)
Press the POWER/MODE button to reset the gas alarm.
