Dave can you explain us the benefits of this meter among other competitors for the community to buy this meter instead?

it seems it is a 6000 count , an NCV or EMFD .

Hope to hear from you.

Nice work.

You gotta admit, most of us are really looking forward to this teardown video :D

I believe there is a video on the way that should cover it.

I'm another that says DO NOT do crowd funding on this one. You risk giving your users funding fatigue, putting your more important meter at risk.
I don't really equate a "pre-sale" of an existing product vs. a "crowd-funded" product in development.
I would participate in a "pre-sale" without prejudice against a future "crowd-funded" project.
Where do I sign-up?

The backlight continuity feature is pretty nifty.  :-+

Why dont you sell what you have, let the people test it for a while and after receiving feedback and do more modifications if needed than order bigger stock. I would buy one to support you.

Seems to be copied from Agilent / Keysight (my U1232  has this feature also)

I got a parcel this morning at 8:15am and it woke me up, anyway I was probably dreaming anyhow.... :palm:



I have no intention of doing a review on this meter as others are better equipped and versed than I am, so far she looks pretty good and is smack on with my Fluke 117 even in range transitions, the leads are very nice, more to follow by others I expect.

I would buy one of those overpriced Brymen RS232 kits if it came with a firmware update to add the backlight continuity indicator to the BM257s. :-//

I loved this feature on the U1272A's and it's very nice to see it being incorporated here, backlight is very bright white LED.

Just curious - Any reason why the sockets are so far up the body?

Seem to crowd the range switch a bit.

Nice side by side comparison. I like the larger digits on the Brymen.

In a video around here somewhere, I thought I saw a giant fuse down there at the bottom.

Interesting. In the comparison picture one can infer the creepage distance between the lead inputs and the rotary switch are much smaller than the Fluke?  ::)

You cannot because this design uses a riser board for the input jacks. Why don't watch Dave's teardown to see the internals?

Based on using the Greenlee DM200A which has the same physical layout, yet, the leads do get in the way of the range switch.  The switch is also on the stiff side.  I still like the meter's design.

That might explain why it appears on this model - but the question is why they are up that high at all.  ie What was the original design decision to place them there.

BTW - I do like the presentation.

Well, one advantage of having the jacks up a little higher is that the strain reliefs don't hit the table when you have the meter up on the tilting bail. On the Fluke 11x if you use leads with larger strain reliefs on the banana plugs you have to rotate the plugs like / \  to clear the table.

The fuse positioning etc.
This is the only CAT IV rated meter in this small a package AFAIK. That's also the reason for the riser board.

The video that is not publicly available? Yeah, right.

Note to self: irony does not come across well in writing...

There is no public or private teardown video.
The internal construction is near identical to the BM257 I have done a teardown on.

Dave, do you have any details on how the battery life was determined? Did you put it through a mixed use of capacitance, backlight, regular functions (V/A/R), continuity or did an estimate of the average power consumption versus a specific battery charge?

I left it running in MIN/MAX mode until the low battery indicator came on.
I used the backlight and various functions a few times.

I guess the proper way of doing it would be a pre-order in your shop. Most of us want to support you, with a nice DMM purchase, so waiting 2-3 months for it is OK.
