Automatic Gas Exhaust Mode
If there is any gas remaining in the Gas Leak Detector when the power is turned
OFF, it will enter automatic gas exhaust mode. When it enters automatic gas
exhaust mode, the buzzer will sound once, “60” will be displayed on the LCD, and a
countdown will start (59, 58...).
Procedure after Sampling High Concentrations of Gas
If a high concentration gas of any in the following table is detected, leave the Gas
Leak Detector in clean air for a certain period of time before turning OFF the power.
Turning OFF the power immediately may affect performance. Also, a sensor error
(refer to page 15) may occur.
