• Measuring range: 0-9999kWh
• Resolution: 1Wh
• Measurement accuracy:1%
• Reset energy: use software to reset.

• Voltage threshold can be set, divide into high voltage and low voltage threshold, when the measured voltage exceeds the threshold, it can alarm
• The default high voltage threshold is 300V, the default low voltage threshold is 7V.
• Communication interface: RS485 interface.

• Physical layer protocol
• Physical layer use UART to RS485 communication interface.
• Baud rate is 9600, 8 data bits, 2 stop bit, no parity.

1. RS485 interface is passive output, need external connect 5V power supply and the the external power supply should ＞100mA.
2. When the input test voltage is less than 7V, it must supply 5V independent work voltage  through MICRO USB port;
