Function:

1. Electrical parameter measurement function such as voltage, current, connected load and total consuption.
   
2. The power button clear function.
   
3. Power-down data storage function (cumulative power down before saving).
   
4. The serial communication function (comes with TTL serial interface, via various terminals communicate with the adapter plate, read, and set the parameters).

Display Format

Button:

A built-in button on the panel, used to make an electricity clear function.
Electricity clear method: Press ZERO key five seconds, then release the button!
Press again to clear the key, the data is cleared and exit charge cleared, cleared so far completed.

Serial Communication:

The module is equipped with a TTL serial data communication interface via the serial port can be read and set the relevant parameters; but if you want a device with a USB or RS232 (such as computers) to communicate, then you need to be equipped with different TTL adapter hardware board (USB communication needs with TTL to USB adapter plate; RS232 communication needs with TTL to RS232 adapter plate), the adapter plate of the specific connection details can be found in FIG.

Considerations:

1. This module is suitable for indoor, not outdoor use.
2. the applied load should not exceed the rated power.
3. The wiring can not be wrong.
