should I take your statement as a confirmation that the 121GW is indeed slow?

I wouldn't know.

A whole load of people seem to have bought this meter without watching any of the videos Dave/joe has been posting or reading any of the threads on what it is or where it comes from. I guess that's the EEVBLOG effect in action.

The speed of the auto-ranging is a fairly basic question, but I guess you did not pay much attention to the videos yourself(?)

I think it's quite reasonable to expect a meter with the EEVBLOG branding on it to meet certain minimum standards, like acceptable autorange speed.
This is the reason for unbiased reviews.  The meter has a lot of features and minimum standards will mean something different depending who you ask.  Even if Dave felt uncomfortable with producing a review because of the bias (perceived or otherwise), I was hoping he would send a few off to the large YT channels to review before offering them.  I thought the guy that offered that high speed camera had the right idea.  Sure there were sites that it was wasted on but a few sites really took the time to show it off.   I think that paid off. 

I think we are just starting to scratch the surface on the UEI meter.  Give it a few months.   I did go back and look at my Gossen BTW doing a side by side comparison and I would say the settling time is a wash between the two.   The Gossen is ever so slightly faster (half second or so).
The point I was making is that you'd expect that  Dave, would tell the manufacturer that it needs to meet certain minimum standards.
It has features that make it unique, but if it's inadequate in other areas, it lessens its value as a general-purpose meter that improves upon the competition and becomes more of a niche instrument that only gets used when the unique features are needed

I agree with you and assume that the time required the the meter to settle was considered to meet their minimum standards.  However, that does not mean it meets your minimum standards.

Do we know the actual update rate on the bargraph?  the manual only states “fast updating" and then there is the “5 times per second nominal”.   
Could we get a figure or estimate on the bargraph update speed? (or is this info also >hidden< in some now deleted videos or comments thread)

I read the manual and you appear correct.  I had made a video showing the speed of the prototype compared with my BM869s and UT181A.  These are some of the fastest ones I have come across.   I can tell you that the prototype was not as fast but still impressive.    I could make that clip public but would rather someone run the released version instead as the results may be different.

We know Dave have seen many prototypes, so he must be familiar with the update speed, except if it is due to the last change to the ohm range (Something about the the highest ohm range).

Anyway I would say around 3 second in ohm range would be fairly normal.

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.

Would a 7 sec autorange meet anyone's minimum standards ?

I assume it met Gossen's minimum as well as again, the one I have is on par with the UEI.   I am not suggesting that I wouldn't want a meter that could auto range faster but the speed of the UEI would not prevent me from using it.  For what you use it for, it seems this is not be the case.  There are a lot of products out there and there is certainly nothing wrong with finding one that suits you.

As a side note, some of the meters I have looked at were painfully slow in the capacitance mode as well.  It's not a feature I typically use so it's never caused me any problems.

Thanks for the info, the bargraph on BM869s updates 60 times/sec according to the manual, so hopefully the 121GW at least is considerably faster than the nominal 5 times/sec stated for its main display, which seems to beg the question (again) why is the auto-ranging then so slow?

A short clip comparing the autorange speed of some portable DMMs I have. Sorry about the shaking; I did not have my tripod with me. Ah, the video has no audio.



(edit) I posted a video with better quality, no shaking and better lighting. I also added 100k ohm measurements to the mix and audio to facilitate the timekeeping.

And does REPEATING the same point 8-10 times on different threads with ZERO hands on use make you useful in the discussion or just LOUD?

Not his fault we have multiple threads talking about the same thing, and his comment is SPOT on, don't need to own one to make that observation.

But to keep harping on that same point?? It seems more about trying to whip up some sort of online frenzy about a point that will take a little time to fix in firmware, bleating incessantly about it won't make it magically fixed or even happen sooner.

Did you try the u1282a in both the 9 and 40 updates per second modes?

Thanks rsjsouza for the timing video, I have calculated U1273A and U1282A as they both goes down to milliohms resolution. Eyeballing when they seem to present a reasonable "useful" value.

U1273A
0-5vdc  = 1.6 Sec
0-30vdc = 1.5 Sec
0-89vac = 2.3 sec
0 ohms  = 1.6 sec & 1.8,sec
20Kohms = 0.9 sec & 0.8 sec

U1282A
0-5vdc  = 0.7 Sec
0-30vdc = 2.5 Sec
0-89vac = 4.5 sec
0 ohms  = 3.5 sec & 3.6 sec
20Kohms = 2.2 sec & 2.2 sec

121GW
0 ohms = 7.4 sec

 

edit: added 121GW 0 ohms from other video (Robert Culver)

I didn't, as at 40u/s the number of counts is reduced by tenfold, which turns it into an oversized UT136C.  :-DD

At any rate, I just ran it here and it mostly affected the voltage measurements:
instantaneous for 5VDC
0.5s for 30VDC
2s for 89VAC

The ohms performance is only marginally improved:
About 3s from infinite to zero
About 1.5s from infinite to 20k

I am looking forward to seeing reviews of the more complex features, for example reading the power of a 110/220 LED bulb, showing  the BT,  trying some long term data logging to the memory card (over night sort of thing).   For those of you who have received their meters and have taken the time to run some  of these early test,  I appreciate your efforts.

I tried the SD card data logging overnight with 5V and 50V.
My room temperature was moving between 24C to 19C in the morning.

I change the file from csv to zip file to attach here because of the file size.

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,

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.
