Key

1.     Backlight control

Short press the key  to turn on or off the backlight, the backlight has memory function, it can store the on or off state when power off.

2.     Reset energy

Step1: Long press the key  for at least 3 seconds until the number in energy display area flash, then release the key.

Step2: If short press the key  again, then the energy value is cleared and exit the reset state. If short press the key  again, then the energy value will not be cleared and will exit the reset state. If there is no operation on the key within 10 seconds, the energy value will not be cleared and will exit the reset state.

3.     Set power alarm threshold

Step1: Long press the key   at least 3 seconds until the number in power display area flash, then release the key

Step2: Power area display the current power alarm value and the last digit begin to flash, then you can short press the key    to plus 1, short press the key   can switch the digit which you want to set. The threshold can’t be over 2.5kw( note: the default value is 2.5kw).

Step3: After finish the setting, long press the key    over 3 seconds or there is no operation over 10 seconds, it will store data automatically and exit the set state.

4.     Power/Energy switch

You can short press the key    to switch display the power/ energy, the display state will be store when power off.
