Well, if I did, I would have mentioned it, so no.
It is pretty simple really.
It measures current on the black wire and is powered by the red wire. This is a well known trick that allows you to use 1 ground for 2 measurements without need for switching pairs of contacts.
You can use it like "jumper cables" between source and load, too if thats important to you to see 4 wires in use.
I read all the info I could find.
Trust me, it only needs 3 wires.
