C.Other Function

1.Backlight control

Short press the key to turn on or off the backlight.

2.Set full/cut off voltage

Before use it, please set the full and cut off voltage depend on the battery specification, the default specification is single 18650 battery (full
voltage 4.2V, cut off voltage 2.75V)

Step1: Long press the key(2 seconds)to enter the full voltage setting interface, display such as: H 4.20V,then release the key

Step2: The digit circularly flickers (automatically move without key operation for 2 seconds), in order: high digit → middle digit → low digit → decimal point, short press to set the value and decimal point

Step3: After setting, long press the key (2 seconds) to enter the cut off voltage setting interface, display such as: L 2.75v, then release the key, and the setting method same as above

Step4: After setting, long press the key (2 seconds) to save and exit; if there is any problem with the setting data, (e.g. cut-off voltage > full voltage), it cannot exit. After display "Err", it will return to the full voltage setting interface and prompts the user to modify the full/cut-off voltage

3.Calibration

All products have been calibrated before leaving the factory. If you think there is deviation, you can calibrate by yourself. The methods are as follows:

Step 1: Long press the key when the meter is powered off

Step 2: Input the standard DC 20V voltage at the battery test terminal (Note: it is not the power terminal, otherwise,the meter will be damaged)

Step 3: The LCD displays CAL → PASS and returns to the normal display interface that means the calibration is successful, then release the key
