inspect for any broken traces, or start more detailed diagnostic and probing to see where is the problem

Do these pics show anything? It all looks OK to me on visual inspection.

But I'm a complete newbie!

Hi

The resistor R38 is not populated and looks like it took some solder on the left pad:

Is this correct on the new video?

Thanks for reply. R38 and R36 are not populated in the video.

I noticed that R30 is jumpered on my meter but is populated with a MELF resistor in the video....

I have written a review of this meter: https://lygte-info.dk/review/DMMAnengQ1%20UK.html

Greetings!

Recently I bought one of these because I found the reviews interesting.

Everything arrived okay, however, there is a mistake in reading capacitors.

Ex: 18uFx250V => The capacitance is 32uF ...
820uF x 2V5 => The capacitance is 1380uF ...

In another multimeter (Minipa ET-2075B) or some Nano values, capacitance is OK!!!

Does anyone else have this problem ???

I bought a few, so far all very good.  Now I don't have run around looking for the Fluke.
A lot of drop shipper selling online in English are not selling the best quality units.  You never know are they reselling rejects by buying at rock bottom price ( I think mostly they are).  I bought my first China-meter from drop shipper online and the meter failed almost immediately.  And that scare me off China branded product for a very long time.  After I took the pain to buy direct, I am hooked.  Sometime they might just replace item if they are shorted, but mostly the quantity and quality have no issue.  If there are some issue, it does not take long for the seller to issue refund with not much proof from my side, some just by taking my words at face-value.

I bought a Aneng 870 recently. What a great deal with 19999 count. It was better calibrated than my fluke 87 and measured favourable to my Agilent 34401. I would recommend this over the smaller meters with only 9999 counts ;)

cheers

I always buy from the ANENG official store on Aliexpress.

(at least, I believe that's an official ANENG store)

Why wouldn't it be accurate?

Exactly; absolute accuracy has nothing to do with other aspects of the meter, including long-term accuracy, which is what I think you were thinking about when posted this. (but I may be wrong)

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...

It cannot be very occurate by design and it is not, no question. Not only not occurate and pure design,  it has also bugs and is not safe. It is very expensive piece of plastic.

Yes, the Aneng meter is a total waste of time, and anyone even thinking of it is best avoided...
Err, remind me again why you are frequenting this thread?  :P

Dave seemed to think they were accurate enough:

A problem with everyone doing cheap chinese multimeter reviews is that nobody really tests the functions, as you do with software white-box testing.
Going through the ranges from bottom to top, I found cheezy my AN8008 in fine shape can't read 2mA AC, it's got a flat spot reading zero then jumps up. The 4-count window at zero also can get in your way. The capacitance calibration value is blindly copied from Uni-T, and needs to be different for the particular TVS used in the DMM.

Point is we trust these DMM's to work and the firmware is never great on the first rollout.

Of course the meter is tested, with 0.01% resistors and precision voltmeters.

Going through the ranges from bottom to top, I found cheezy my AN8008 in fine shape can't read 2mA AC, it's got a flat spot reading zero then jumps up.

Try using the mV range, the you problems is down to a few uV, anyway I would not complain about the meter zeroes a few count around zero especially not a few uV.

Dave mentioned several times in his video that the AN8008 lacks a proper mA range (and yes, it's a problem!)

It lacks functions. Spend a couple of $$ more and get an 860B+ instead.

I've seen one of those, they're horrible. Ew!  :--

Proof that you can go too cheap.

(the case is the perfect size for an AN8008+probes though - nice snug fit!)

Precision spot checks do not cover oddball bugs. They get 9,999 counts out of the Hycon DMM chipset using a cute algorithm for oversampling and decimation, and noise blanking for the uV range. Autoranging screws up on ACV if there is a DC component, and you have to reboot it.
Try measure 1-2mA AC at 50-60Hz, I've never seen it tested in any reviews.
