Key function:
1. Backlight control
2. Reset energy
Step1: Long press the key for 5 seconds until the energy value flash, then release the key.
Step2: Short press the key again, then the energy value is cleared and exit the reset flashing state.
Step3:If there is no operation on the key within 5 seconds, it means the energy value is not cleared and will exit the reset state.
3. Set power alarm threshold
Step1: Long press the key until the LCD screen display"SET CLr", then release the key to enter the setting state
Step2: Power window display the current power alarm value and the last digit begin to flash, then you can short press to plus 1, when there is no operating over 3 seconds, it will switch the digit position
