Additionally, if in the continuity mode with the tone option selected and then either the manual or trigger hold called up and used the continuity tone will latch continuously on a momentary closure and stay latched even after then going open yet it does not do this when auto trigger is enabled nor if the beeper on short option is nominated and triggered. I don’t mind this latching continuity on a momentary closure feature and have used it before on larger sites but would much prefer a louder more reliable beeper instead of the existing pinball tone and I do have a couple of other meters with this capability, permanently latching the continuity beeper operationally on this meter is unreliable and a bit hit and miss so I doubt that it was intended as a feature.

Another member of the forum has made a video which displays how the continuity tone option functions on the U1282A pretty much as I described in a prior post, I'm still mastering the stairway to heaven extended mix and currently have jingle bells down pat.   :-+

I think we all can congratulate haoleboy becoming a volt-nut  :) Need moar DMMs!  :box:

I was not expecting it to stay spot on for this long, but it is pretty nice to know that every single digit it shows is correct. Usually with multimeters i ignore what the last digit says since its usually out.

Fluke 87 V is up 20,000 counts and Keysight U1282A 60,000 counts.

I know this topic is quite old, but it's one of the only ones that seems to discuss the issue I'm concerned about - in fact, I registered here just to get this question answered:

I've seen the video of the U1273A with the variable tones, depending on continuity.  Can anyone confirm that the U1282A also has this functionality?  I can't tell from the manual, and since I work outdoors a lot, I would prefer the LCD meter.
