Seriously, anyone know the story and meaning of "OL" on multimeters?
(1/8) > >>
TheAmmoniacal:
It's used on every multimeter - yet everyone calls it something different. What is it?
The Soulman:
Imho its over limit, better would be out of range.
VK3DRB:
I remember a rather boastful electronic engineer at IBM seeing OL on fluke DMM, saying something like "OL means the meter is faulty".

OL is a defacto standard that works with seven segment displays quite nicely.

We use a lot of defacto standards without thinking about it. One defacto standard I hate is SMD tantalum caps having the stripe as positive, yet on electrolytic caps it in negative. Who ever devised the tantalum "standard" needs to be removed from the gene pool. It is illogical, stupid and dangerous. I think many of us have been caught out with that once.

I can't believe overload is leading the poll. A meter is decidedly not overloaded with an open circuit on resistance mode. The measurement however is certainly over limit. Over limit works for all modes.

It's probably the leader because that's what it means.  At least according to what the manufacturers say in their manuals.

Keysight: "OL - Overload (the reading exceeds the display range)"

Fluke: "If the input signal is greater than the selected range can measure,the Meter displays overload"
