Ahhh, the rugged individualist type! Generally speaking, if the ends meet
and there is no gap between the ends to accommodate a wire, then it should
clamp around the wire entirely to get the proper reading. Alternatively, if
it is a 'brand' name you may be able to find the instructions in PDF format
on the company website.

Instructions? This is my husband's meter. Now, I know that there are men
out there that read instructions...but it ain't my hubby. He's the
stereotypical guy...the instructions were thrown away because they were
part of the packing material. In fact, it was, "Well, where are the
instructions?" question on my part that started the whole "discussion". ;-)
