I tried the SD card data logging overnight with 5V and 50V.

Thanks!!  This is very good news.  After hearing about the VA, I was starting to wonder.

I am looking forward to get the meter in a month or two and check it out (I will do a review). The main reasons I got the meter was the low burden voltage and the 15V diode mode. I wonder if the VA mode is useful, I will probably continue to use my meter with a real W mode.

I'm looking forward to your review.
Thanks for all your other reviews on your website. It's my first stop whenever I need a new battery or charger. :-)

It was also a happy surprise for me with the really consist measurement numbers considering 50,000 counts with 0.05% in the spec.

I also hope to make the multimeter reviews useful for selecting a meter, but I need more for that, at the moment there is only 18 reviews.

Well we have the miliohm meter in common, the YR1030 that you can test interns,battery resistance with.’oh, but the way. Ignore my message on the other site, I found the manual and translated it.
In fact if you want a copy to post on your review in PDF fr]ormst just let me know.
Thanks,
Scott

HKJ - something that would help me and maybe others - put a link to your great website in your profile so it shows up every time you write something.  Every time you write something, I try to find it and fail. (also I want to add it to #3).
If not how about give it to me one last time.

Thanks and keep up the outstanding work. For those that do not know - HKJ has the best site for battery and battery charger reviews.

Click the globe to the left, it leads directly to my website (I fixed that last time I got a complain about it).
The website do not use a framework to give a good layout, but is old style html, this makes it very fast to navigate if you know how to use your browser.
I publish many reviews, that is not the same as they are superficial, due to automation there is usual a lot of testing behind each review.

That seems to be the most critical issue found in 121GW so far.. :-DD
Folks I am getting back in Electronics game after 18 odd years :)

Yes I think this a good feature for a meter.

Edit: Because I am an MP3 player addict like the MM addicts here.  I think I have bought every MP3 player made since the Rio

..Well the Micsig tablet scopes can play videos, but I suspect the 121GW's processor doesn't have the power to decode MP3s. WAVs, maybe..

I agree.  Dave could start the EEVTunes store to buy your favorite music.

If I remember correctly there's a 32-bit ARM inside it. Most of those can decode MP3s, even without an FPU. Talking about low-bitrate here.
My opinion is that, if this thing lands in enough hands, even without source code and firmware, some people will manage to built a custom firmware for it. It has happened to every thing that was affordable and/or appealing. Either that, or something better, cheaper and more hackable comes along.

Can’t have the EEVBlog music store for this meter unit we can use the Bluetooth to either transfer the music to the meter, or play music on it and pair it with a speaker or headset. Then the Bluetooth would have a purpose. From what I’ve read it’s slow update refresh using it with the app so far, and you can’t transfer the logs from the meter to a computer (I don’t believe this one was never in scope). But if they can’t fkx the slow refresh rate on the app I’ll gladly give that up for playing music a BT headset, and put a bugger SD card in it.

If folks want a MP3 player plus a multimeter, why not buy a mooshimeter instead? :-DD

Just did a few minutes of research on this, it's probably not possible to do significant MP3 decoding unless you have an M4F and above. Only those have the single-cycle MAC instruction. It's mostly fixed-point arithmetic, but it needs to happen pretty fast. Was just a theoretical question anyway, I doubt anyone will try to implement this.

I think Scott said he played with one.   

I have not seen anyone make a video of the BT yet.   I thought they were only planning to use it for logging and not to do updates or even pull the contents from the card?  If it is only used for logging, the speed may not be a problem.   

The Gossen meter sounds as fast in autorange.  It's BT could also be used to log but the meter was such power hog, it won't run for very long between battery changes.  They do have that external power port so you can plug it into your portable Nuke for extended logging.   :-DD   Then there's my cheap $120 CEM with it's 900MHz radio running off a single 9V for days with logging.  :-DD   It will be interesting to see how the UEI meter stacks up with speed, battery life and distance.

Another new review!  :-+   They are starting to trickle in.

Just finished watching it.  He compares it with a BM867s and shows some speed comparisons.  He also shows the power measurement.  9.846W vs 9.42W seems like a lot of error doesn't it?     

It's been a while but it seems like they were not accounting for the losses in the meter.   I made a few videos showing the basic circuit and such to try and isolate it further after I was told I had it connected wrong.   I would be interested in seeing someone with the production meter dive into the power measurement in more detail.  A video specifically for that one feature, showing all your connections and such.   

It's a shame they capped it at 50V.  I was all along thinking AC line power measurements.

Just a quick comment about the power measurement.
I did this mainly to show it working and how the update speed is.
I didn't use the sense pins on the electronic load. This means, the cable and connector loss from the multimeter to the load are included in the Multimeter measurement, but not in the DC-load display.
Because of that, it is absoluteliy expected, that the load shows a lower value.
I'll add a comment to the video to make that clear.

If you wouldn't mind,  I would like to see you try it with the best case conditions you can come up with and see what results you get.   Explain your setup in the video if you decide to make another. 

Thanks for the video BTW.  I gave it the old TU.
