To put it more mildly, OL does not stand for "overload" (which would make some sense for zero resistance), but for "over limit" - higher resistance than what the meter can measure.

You're right, I'm not sure why I typed that.
I guess I wasn't thinking clearly on that one!
[quote BigGuynRusty][quote mikebw]Zero ohms means no resistance, and on many digital multimeters "OL" or overload also means zero resistance. You just failed my "Basic MutiMeter Class" mikebw!!
Zero Ohms is Zero Ohms.
~BUT~
OL means INFINITE Resistance, NOT Zero!!
To put it in other words.:
Zero Ohms is a "Short".
Infinite Ohms is an "Open".
I don't know of one Digital or Analog meter where "OL" means Zero Ohms while reading resistance!

Feel better now, Rusty? Perhaps someone should point out that you don't even know how to spell "multimeter," hm?
