Reset energy
Step1: Long press the key until the power display area display “CLr”, then release the key.
Step2: At this moment, the energy is flashing to prompt this is the energy reset state, if short press the key again, then the
energy value is cleared and exit the reset flashing state.
Step 3: If there is no operation within 5 seconds, it means the energy value is not cleared and will exit the reset state.
Set voltage alarm threshold
Step1: Long press the key until the power display area display “SET”, then release the key.
Step2: After enter this state, the voltage area display the current high voltage alarm value, the current area display the current
low voltage alarm value and the last digit begin to flash, then you can short press to plus 1, when there is no operation over 3 seconds, it will switch the digit position automatically, from the high voltage alarm value to the low voltage alarm value, there are total six digits, the range of the voltage alarm threshold is 6.5~99.9V;
Step3: After finish the setting, long press the key until the screen display “PASS”, that means you set successfully and will exit the setting state automatically.
