I spent a lot of time writing about how to use this device. But just as I was about to send it my browser took a powder and I lost it. I'm too lazy to write it all again...but it was truly brilliant.In short, you can likely put this to work with no difficulty. But if you have difficulty, you'll have to learn the device by grope...the documentation is that bad. Where you'll get stuck is getting the receiver (i.e. the display) and the transmitter (i.e. the sensor and relay control) onto the same channel. They come from the factory matched, but in groping you can create a mismatch.Here's your clue. The "FCH" field is what the receiver/display thinks the channel is. If it's not the same as the transmitter, you scan with "SFH" field until you find the transmitter. You then use the "SFH" field to change the transmitter channel. And finally you set the "FCH" field to the channel (1 to 150) you arrive at...i.e to match the "SFH". You can't just set them to the same value.Good luck. Don't send it back. Rather beg for decent documentation or make a game out of figuring out what all the fields do.And as far as size (i.e. current capacity) goes, error on the high side...but not too much. None of the current actually goes through the device. Rather it goes through a Hall Sensor. But if you buy undersized, the displays will overflow. If you get it too large you won't be able to display small current changes. It has 5 significant digits I think. It's all about resolution...not capacity.

After 2 weeks of manual reading, you tube videos, and trying any solution i could think of i am giving up. Manual online- my product does not look the same. Actually got the power up using external power connector, but i get no readings. Changed the jumper position, no readings. NO customer support, only buy if you are an electrical engineer. If i could give it no stars, i would.
