Poll: Handheld meters with minimally-annoying auto power off (APO)
(1/11) > >>

Following up on the handheld-vs-benchtop meter debate...

Let's make a list of handheld meters that will auto-power-off silently then wake up in the same mode with a single button press, ie. they aren't annoying to use on the bench all day long.

:) Meters that DO this:
Brymen: BM857  BM789  BM235  BM869s


Caveat: They lose some settings, eg. manual/autorange mode and min/max/rel values (but if you're doing a long min/max session you need to temporarily disable APO anyway).

:( Meters that power back on with a button but lose the secondary function setting (eg. they APO in continuity mode then come back on in Ohms mode):
Fluke: 87, 187, 189, 289


:-\ Meters that don't have APO (or can disable APO permanently) and have a really long battery life (1000 hours or more):
Fluke: 27FM   37FM

Other: DT830 ("Harbor Freight")


:( Meters that beep when turning off and/or require you to turn the dial to wake them up:
Fluke: 101
Kaiweets: HT118E


>:( Special hell:  Meters that beep twice - once to warn you they're about to APO then again a minute later when they actually do it.
Aneng: AN860  AN870  V04A   AN8008
Surpeer: AV4

Fungus:
I'll be testing my meters today, feel free to post results for other models.

Edit: Yes, there's meters that allow you to temporarily disable APO by holding down a button at power on. I haven't included those because that's annoying too. I don't think it excuses them from not doing it properly.

BM789 does this. off silently.
Every day, I do not turn off the DMM several times and many times a day I turn it on simply by pressing the yellow button.

Let's make a list of handheld meters that will auto-power-off silently then wake up exactly where they were with a single button press, ie. they aren't annoying to use on the bench all day long.

Any meter that turns of automatically is annoying for bench use. The same for meters that run out of batteries.  >:D I learned that a long time ago.

The point is that some are much more annoying than others.
