I need to buy a multimeter. I noticed that for the resistance some
have 2000k and some have 20M, which I believe are totally
different. Which one is better to have? Or does it even matter?
I'm mostly interested in testing something that's around 2M. So I
don't know if it matters which multimeter I get.

For resistance measurements, more is better. A short circuit is
ideally zero ohms, and it goes up from there.

Practically speaking, you might never need to measure more than 2
MegOhms, which is a high enough value for most uses.


You're confusing the *resistance* range of a meter to its
*impedance*. Both are measured in ohms. The impedance has nothing to
do with how high a resistance the meter will measure.


No, the OPs question is concerning the upper limit in resistance
measurements, *not* the meter's impedence.

I think you might want to reconsider who is confused here.


I was thinking that several people were confused.
