To confirm; all of these are 'Autoranging'??

I was looking for non autoranging since I don't like the delay waiting for the meter to do what I already did. And yes, I know the single disadvantage, but in 30 years, I never wiped one out.. ;)

Yes, as stated in the intro on post one, all meters are autoranging. Most, if not all, also have manual ranging, for some specific applications.

Hi,

I did not see my favorite meter(Because I got it super cheap last Christmas), the Holdpeak 6688G. 
https://holdpeak-store.com/hp-6688g-multimeter-1000v-20a-capacitance-ammeter/

While it has some problems(the continuity beeper is a nightmare), it's hard to approach 40000 counts for around $50.  And since I use it more or less as bench meter, the fact that it's a BRICK, is not down check for me.

Thanks. It will be included in the next revision. Remember that a high count meter without a decent voltage reference will drift eventually. Not impressed with the internal construction. Beware.

I think that table should list only the "best" DMMs

What is best? several specs e.g.: very small long term drift.

Today there are a LOT of DMMs with +50K counts, but in 5 years, how many will keep the calibration?

Yes, I know that the Holdpeak HP-6688G has problems.  Poor QC is at the top of the list.  As far as the design goes, let's not go there.

As soon as I received it, I popped it open.  I just wish I would have taken photos. 
I found 2(TWO OF THEM!?!  :wtf:) tombstoned caps right off, which I fixed.

I picked it up CHEAP(about $16 Prime) from Amazon a couple of years ago.

A recent use I put it to recently was when I started gathering the materials to make one of Conrad's Kelvin-Varley Dividers.  Instead of building one of the bridge circuits to sort the various resistors I just used the meter after making a simple fixture to easily change the resistors out.  For things like this, it works just fine.

I've been wondering for some time now: Does any of the Chinese OEM use feedback given on electronics forums like this to improve/fix stuff in their meters?

Probably yes, given that I have seen a lot of marketing sentences and design changes reflecting what is commonly said around here - things such as ceramic fuses, demonstration of protection in all ranges, etc. It is basically free consulting services for anyone in the business.

Oh, the "whys" of the datasheets... The information is there not to be an axiomatic truth, but instead each speck of data must be slowly inhaled while carefully performing a deep search inside oneself to find the true metaphysical sense...

Having spent a fair amount of time in China, I doubt very much manufacturers spend any time following discussions on electronics forums.
First of all, few people understand English and YouTube videos are not readily accessible.
With few exceptions, companies cater mostly for the local market and local regulations.
They may sometime be influenced by requests from large retailers from India, for instance.

I do not know if they follow youtube, but I (my reviews and direct communication) have been the reason for some changes in battery chargers.

Have you had similar experiences with multimeter manufacturers?
Where in China was the product from?

No, but then I have never received a multimeter for review, all my DMM reviews are done on meters I bought. With chargers some manufactures often send me one for review.
I do not remember the locations, but probably Shenzhen (I do not want to specify any brand names).
