The Key
There is a key on the panel, it can be used to reset energy.
The method of reset energy: Long press the key for 5 seconds until the digital on energy display window flicker, then release the key. Short press the key again, then the energy data is cleared and quit the flickering state, now the reset operation is completed; if long press for 5 seconds again until no longer flicker, it means exit the reset state.
Serial communication
This module is equipped with TTL serial data communication interface, you can read and set the relevant parameters via the serial port; but if you want to communicate with a device which has USB or RS232 (such as computer), you need to be equipped with different TTL pin board (USB communication needs to be equipped with TTL to USB pin board; RS232 communication needs to be equipped with TTL to RS232 pin board)
