Zero adjustment
You can adjust the zero setting according to the actual detection value.
Enter the zero trim submenu, select the gas type, the value, and unit of
measurement. Then, save the adjusted value.
For example, if the displayed value is 3 instead of 0, you can set –0004 and
save this value: after that the displayed detection value will be 0.
Alarm value setting
You can set the low alarm values and the high alarm values for the device to generate the audible and visible alarm signal when the gas concentration exceeds the set alarm values.
Usage
Gas detection mode is set by default. The system returns to the gas detection mode after 5 seconds of idle time. The device will automatically analyze the gas environment and display the result on the screen.
Normal gas concentration
If the gas concentration is below the low alarm value, the detection result will be displayed on the screen.
Abnormal gas concentration
If the gas concentration is above the alarm value, the LED indicators and the backlight will light on, the device will vibrate and emit a beeping sound, and the current detection value will be displayed on the screen.
