As far as checking the two previously unused leads, it depends upon how
the meter being used for the test behaves when checking a zero ohm
connection.. many DMM meters may consistently display up to about 7 ohms
with the lead tips pressed together.


Wow! I have never had a meter zero that far off. Digital or analog. I've
had cheap meters and good meters over the years, and some of the cheap
digital ones did not zero, but it was usually in fractions of an ohm. 7
ohms would be a heck of a lot to have to remember to account for all of them
time.
