Brymen had provided me with the alignment procedure for the BM869s under the strict pretense that I not release it, which I agreed.  Morally, I stand by my commitments.  I suspect the concern the companies have with letting this information loose is there are certain people that feel they can align a meter without having access to the tools needed.  They proceed to fuck up their meter, which is no big deal, but then they start posting about how inaccurate it is.  I imagine this could damage the companies reputation.   

(calibration and alignment are not the same thing....)

Thanks for pointing that out. I reviewed my correspondence with Brymen and I too had agreed to not provide this information. I had forgotten that I had agreed to this stipulation.

Please accept my apologies for offering something I should not have.

Brymen has the BM857s if you want a simple, "almost-function-per-position" meter to complete with a Fluke 87V.

"Dual display", etc., sounds like a cool feature but if you don't use it very often then it's just display clutter and OP has a Fluke 289 for that.

DC accuracy is on par with a BM869S.

I've had mine for about 8 years and as far as I can tell it's still accurate down the last digit in 50,000 count mode, and 500,000 count mode is pretty close. I don't believe any other Brymen will be superior in that respect.

Thinks I like:
Simplicity of the function selector, simplicity of the display
Really high-contrast/readable display (Flukes fall down a bit here IMHO)
Speed
Lights up any LED in diode mode


Things I don't:
Short backlight time, can't disable the timeout
The stand is maybe a bit small (although I don't use it much thanks to the good display angles)

Looks are a matter of taste but IMHO the Brymen "industrial" meters look better in person than the front-on pics they put on their web site, and their "curvy" meters look worse.

Rather than paying for a warranty, buy three 869's and compare them from time to time to make sure their readings align. If one happens to go wrong, recycle it and buy a replacement.

No need if OP owns Fluke 289's (plural)

BTW another function where the BM869s does not shine is sub-nF capacitance meaurement. It just doesn't have enough resolution there: the lowest range, which is 50 nF, is way too high. So much so that I'd say that it's completely useless below ~100 pF and can only give a rough estimate below 1 nF -- you need a separate device to measure in these ranges.

That applies to any handheld DMM. Holding the probes is enough to screw up any measurement below a few nF's.

How does the continuity beeper work? The only meter I've got with a descent response is a Fluke. All the others I've used are too slow and can not be used to track down bad contacts.

Do Brymen DMM's go up in smoke if it's on resistance and you plug into a wall socket? That will happen anyhow sooner or later.

Brymens are as good as Flukes for both of those.

...or better. eg. The 869s mentioned in this thread has a CAT IV 1000V safety rating - higher than any Fluke.
