An excellent assistant, calls all the wires at once, used to fiddle with a multimeter, but then in 5 minutes I found everything. Many handymen here write that this is a useless thing and all that, I will say that you are very wrong, to put it mildly, read the materiel and learn how to use it, as they say in skillful hands and strike a balalaika.
