Correction of measured voltage:

Long press the "+" button until the display starts flashing. You can then use the "+" and "-" buttons to correct the measured voltage. e.g.: adapted to a voltage value measured with a multimeter.

Protection setting:

Disconnecting the battery from the circuit below 12.5V and reconnecting it above 14V:

Set the protection value: press the "+" button once to display the protection value, double-click the "+" button (the decimal point is flashing), then press the "+" or "-" button to set the value to 12.5 to change to . If there is no operation for 3 seconds, the module will automatically save and exit the setting mode.

Adjust the hysteresis value: press the "-" button once to display the hysteresis value, then double-click the "-" button (the decimal point is flashing), then press the "+" or "-" button to set the value to 1, to set it to 5. If there is no operation for 3 seconds, the module will automatically save and exit the setting mode.


Battery switch back delay:

Press and hold the "-" button until the display shows 000. You can then use the "+" and "-" buttons to set the switch-back delay time in minutes.


Reset:

If the device is turned off, press and hold both buttons at the same time, then turn it on. Then "888" will appear on the screen indicating that the factory reset was successful.
