So, the polarity of the cabling is somewhat important, although the selection of red or black for the + or - lead, respectively, is not.

Yeah, but an analog gage? Can you buy them anymore? An old geezer like me wouldn't be able to read the meter without terminal eye strain - I have not used an analog meter for twenty years! The idea of having that little mirrored strip and those skinny little lines and scales and a freaking needle to get all lined up to read makes my sinuses ache. I like the big LCD displays that people with aging eyes can read without a strain.
There is something to be said for reading the manual that came with the tool before you set out to apply it to various items in the car and in the house. If you are new to the tool and don't like reading instructions, buy lots of fuses. Jim
