If you only had one meter?
Xandinator:
You'll be fine as long as you stay away from the TEA thread...
I think it is more about the inability to talk yourself out of it, the true meaning of DMM ultimately being "dispossession of my money".
Technically two BM789 can be seen as only one DMM – e.g. a 28IIex is just a very prominent and safe replacement fuse carrier for a 87V – having two of the same kind is even better because it also holds spare batteries!
coromonadalix:
For theses new Brymen series, sure they seems good, but i can't appreciate where the meter sit on a bench and have a tendency to wiggle on the meter stand, they should have get rid of the round-ish bottom meter case part
The older series had the same complaints
rsjsouza:
All things considered, I think I would go with either the U1272A or the U1282A (if waterproof and a signal generator were needed).
They both have one of the most comprehensive set of functions I know with dual display, data logging good capacitance meter, quite accurate and the battery life is very good.
If battery availability was a severe problem (post-nuclear holocaust or other severe supply chain disruption) then I would have to go with an analog VOM - at least voltages and currents wouldn't need one.

Where and under what conditions? :-//
Lab job, home, shed, under car, dead boat and radio in gale force wind waters,
suspect non labelled 3 phase mains switchboard,
PCB with bloated and 'normal appearance' monster caps,
rich no-life scum cheapass clients hassling you to find problems left by the last tech/s who 'worked cheap' etc
At this point it's 2 meters/meters/? (200cm/2000mm/78.74 inches) of decent quality or nothing for me
Why risk it on one meter that may fail, get dropped/driven over/drowned
or batteries go flat?
That said two AVO8-mk5 analogue needle pointers in a briefcase won't let you down
(especially if shipwrecked on Earth, or spacewrecked on Moon or Mars)
and don't need batteries,
passive features only,
and up to 3kv if you like living terminally dangerously
Active features can be handled by digital Fluke beaters
with 'installed and removed on the day of use' batteries,
assuming there is squeeze room for them in the briefcase,
and no one at interstellar flight control checks the weight :popcorn:

AVOs need batteries for the ohms ranges & things like Fluke 77s last for up to years on a 9v battery.
Your "use & remove" batteries would probably not last much longer, as they would run into "shelf life" problems.
--- End quote ---
Agreed on the shelf life, but the ubiquitous guaranteed 'leakage' is my only concern,
been there too many times, wasting time cleaning up marketed expensive bunny batteries
more often than 2 dollar shop cheapies with pre-schooler grammar labelling
and I did quote:
"and don't need batteries,
passive features only,"
but did forget to mention a flying AVO will down the first shipwreck island attacker or Moon/Mars alien
and maybe the idiot behind him too :clap:
drive in tent or lunar module leg stakes under heavy gale or lunar wind conditions
and still work to measure whatever DC the cobbled trashed radio needs to send out a rescue signal,
and most important:
fetch a good auction price if rescued from the above :-+
nukie:
Fluke 187 and 189. I have both, with refreshed supercap. Very reliable time tested instrument except for the leaky cap.
