Docs for Electricity Meter Brick?

Are there any docs for the Electricity Meter brick. I know that the product web page has a data sheet for the sensor used, but are there schematics and something that tells how the jumper for on/off should be used and what the trimmer pot is for?

Thanks for any help.


Sorry for the inconvenience brought.

The attached file is the schematic of the analog electricity meter. The 3-pin header is used to read the data of the electricity meter, and it is OUTPUT, VCC, GND.
And the trim pot is used to turn on or turn off the meter, you can use a wire jumper to select.
