In a recent video, Dave used what he referred to as the "mystery multimeter". It has the same blue coloured encasing as the Brymen 235 rebranded meter. As another user pointed out, there are many other features that Dave likes:
- Off position is all the way to left
- Selector dial is flush with the body
- Rubber holster protrudes past the face
This can be seen in the recent mailbag video at time 34:40.

Yes, Dave has been working on this for a while. It's a 100% Dave designed meter rather than a co-branded meter like the Brymen. They have been sneaking their way into the videos over the last month or so, but this last video is definitely the most open appearance. He used a "super secret meter" at one point that had a 15V diode tester, so that's probably on the list of features.
Dave mentioned in the Batteroo live stream that he was waiting on a final prototype (probably the one shown in the video you are referring to since it should be here by now), and after testing it Dave is expecting to be ready for a public unveiling. (Sorry, I'm too lazy to find a time stamp for any of this)
The mystery Multi Meter has "low burden" written on the case. He must have included some features of his uCurrent into the upcoming meter.
In the latest mailbag Dave also gave a hint as to the microcontroller it will be powered by (STM32...)
Not far away now! I've been holding off getting the Bryman meter in waiting for this much anticipated Dave DMM...
Intertek as a outsource manufacturer?
The Supporters Lounge has multiple threads where you can read all about it.

Did you happen to see those two videos Dave did on designing a better multimeter? Yeah, BIG hint LOL.

It is?
I thought so. This is one of those things where I've picked up bits of information here and there but can't really remember where any of it came from, so I guess I should be careful what I say. I do believe he has been much more involved in the design of this one at the very least.

...if you are a supporter.
I've seen these threads pop up on the recently updated list, but I can't actually read them.
Saying that Dave designed the meter is going too far. He was influential in deciding on features and certain implementations .
Intertek as a outsource manufacturer?
Intertek is Korean company that does certifications... Like TUV in Germany... It means it was independently tested... Not a meter OEM..

Yes, 15V diode test.
Not entirely true that it's 100% designed by me. I set the specs, and a multimeter company is doing the actual design. But I am getting nitty gritty on the circuit level though.
There is only so much I can do, and many compromises have had to be made, and I've had to let a few things slide that I would have fixed myself if it was me doing the design. But it's hard to go back and forth on tiny changes like that, you can't micro-manage a design team you have no direct contact with.
I'd love to actually blog the process but I can't.

Supposed final prototype is on a truck somewhere.
I have 4-5 other prototypes that look identical, just some minor tweaks on the new one.

In addition to what I said above, yes this is designed from scratch exclusively for me. It's not based on any previous design.
One thing they wanted in the contract though, is they liked the compact 4xAA battery housing I specified and they came up with, so they wanted permission to re-use this on other (non-competing) products of theirs. So you might see the case used in other products.
So, is the cat out of the bag and you are alright with posts about the meter in the normal forums? It may be a sign the product is getting close to release.
Ah, why not, it's been a long time so I'll release this video:

This is looking very promising; thanks for sharing this secret video with us

Sneaky little peek from the last Mail Bag segment:
Again, I presume as that video is publicly available, there is nothing secret squirrel shown here...

As far as I know, the manufacturer has not been identified. Dave has kept that detail close to his chest. Some have made guesses, but it's all speculation.
I see from the PCB print that it has 2 fuse holders. Does that mean abandoning the single fuse mosfet solution you spoke of in #931 was one of the compromises? Or does this sample predate the concepts discussed in that video?
Pre-production working sample shown in the last mailbag has two current inputs, therefore two fuses presumably. 10A and 500mA? (input jack has 400mA screen printed on it).

Yes. The design was too far down the track and has had too many changes to entirely change the design at the last minute.
its very interesting to see how long it takes to design a new mutimeter.
i think the sla print video cloud be 7 years old.
That video was uploaded Nov 18th 2015

So the big question is of course....
Does the Batterizer fit? Or is Bob going to send you an angry letter now requesting for you to change it?
