New Brymen BM2257 Multimeter

[0Anonym]

Sorry if this is a stupid question, but would you guys choose the Gossen Metrawatt METRALINE DM62 over the BM 2257?

[EEVblog]

I didn’t quite understand why I couldn’t find anything about the BM2257, but I didn’t know at the time that it was so new.

Given that Brymen can't send me one for a few weeks means that it's not ready yet. Does anyone actually have stock? Wouldn't surprise me if there are delays. The original BM235 was something like 9 months late from when they promised. And the BM786 was delayed too.

Seems like a much bigger meter.
The thing I like most about the BM235/257/2257 is that it's small, and it has big digits.

No. It's much more expensive and it's a horrible color.

Thanks for the responses.

Can someone explain why some Multimeters have joined AC and DC switch Positions (for example the BM235) and some have split AC and DC switch Positions (like the BM2257)?

To me it seems like, even though its only a very small detail, it seems like a simplification when working in a rush.

It a design decision, there is a certain number of modes that a meter has and they must be distributed over a number of switch positions. Some can be combined, others need a separate position. Then it is up to the designer how to distribute them, some prefer shared AC/DC (May not be possible on a good meter), some prefer to combine ohms/diode/cont. in a single position.

What's the display backlight colour? On the EU website it shows a paper white backlight but in the datasheet it's amber.

On the brymen.com site it says "Warm Amber Backlight".

Thanks. On brymen.eu it's displayed with a (paper)white backlight unless that's just a picture with the backlight turned off. The datasheet however shows the BM2257 with the "warm" amber backlight.

The polish distributor brymen.eu listed it as available for a few days ... currently it is not possible to order it.
Official distributors Welectron and Eleshop do not list at all.

I guess we can expect some delays and probably your sample could be one of the first.

I assume I'm getting the first production batch run.
I wonder if it will have a firmware programming port like the BM786 has?

Does it make any sense to contact the Polish reseller even though someone else from the forum contacted them before or is Brymen known for not sharing Information in advance?

What inforamtion are you looking for?
Why buy from a Polish reseller/distributor if you are German and there are reseelrs/distributots in your own country?
I guess every reseller/distributor will anser you ...

Got it!
Orange backlight is very nice, as is the very fine bargraph.
I note that CATII marking is missing as per the new standard.

What does it look like without the backlight on?  Just a white LCD?
Are they able to offer it with the paper-white backlight or just the amber?

Same transflective sceen as the BM235. BM235 is slightly better at higher angles.
Haven't asked about backlight.

Am I the only one bothered by the A <-> mA inversion?

Well, the 2257 is basically a newer 257, so in that regard the jacks haven't moved.
Also, the BM78x series has this arrangement, so it's probably their current standard.

Teardown might be interesting...

Still bothered

Yeah it's 100% dumb on the same class of DMM.

The world is already confusing enuf......

Talk about confusing; for the third time, the 2257 is based on the 257, not the 235, so there are no jack changes as you can see from this review 12 years ago: https://www.eevblog.com/forum/testgear/brymen-bm-257-pictures-and-mini-review/

but is the 257 not based on the 235? or is the 235 based on the 257? or is there some other intermediate model that we have not seen yet that links them all together?   


cheers,

... and due to the fact that last March I bought a BM869s you can expect soon a BM8869s ...
I am joiking but I'd not be too much surprised 

A BM2869s...  There are some things they could improve slightly...

Yeah definitely. I want a BM869s with auto hold, LowZ voltmeter, maybe faster autoranging and 60k counts, beep in diode mode if the diode is shorted, and... and... I guess that's all: unfortunately, the BM869s is good enough as it is, there's not much to improve upon.

Teardown might be interesting...

Definitely!
