History Chart:

"CHART" with 2 Alarm indicate the status of CO2 records up to 24 hours, every three hours, the detector calculates a set of log data. The chart is used to display the history of CO2 concentration.as shown below:



4 Work mode:

"Auto" auto backlight is the default mode. Press "Up key" to quickly and easily change the current backlight mode, Auto à AL à On à OFF. After selecting the mode, it is the confirmation mode. You do not need to press any key to confirm it.

At the same time, the backlight of AGn31 has 4 working mode, Auto-Alarm-On-OFF. When set to auto working mode, AGN31 will automatically change the backlight color according to the CO2 concentration.
Back Light ModeBacklightBuzzer
AutoThe LCD screen backlight color changes with carbon dioxide concentration. <800ppm: green; 800ppm~1,200ppm: yellow; >1200ppm: red. The red threshold can be modified in ALBuzzer beeps every second when AL is exceeded. Until it is turned off (with mute key) Default is OFF
ALThere is no backlight in normal state, but when the carbon dioxide concentration exceeds the alarm value, the LCD screen backlight is red.
 The AL alarm value is preset to 1,000ppm, please adjust the alarm value according to the alarm value setting method.
Buzzer beeps every second when AL is exceeded. Until it is turned off (with mute key) Default is OFF
ONThe backlight is always on. Only backlight function, without any prompt function. Backlight color depends on selected color, see COLOR setting function.Buzzer beeps every second when AL is exceeded. Until it is turned off (with mute key) Default is OFF
