Where's the 10MOhm input resistor chain? I can't see it.

In the black box, together with the other input divider resistors.
Why aren't we calling out fake regulatory claims, especially when they are obvious?
The DMM is the usual fail - 250VAC fuses (with lots of room for bigger ones) - Intertek would not give 61010 approvals beyond that, unless they were sleeping or bribed.
Wasting a whole switch position on hFE and an NCV function that barely works is unforgivable. My Aneng 870 can detect a live wire from about 10cm away (4 inches).
Edit: That's not quite true. It can detect a pug board with 4 plugs in it from about 10cm away. A single unloaded mains cable makes it beep at 3-4cm depending on the angle of the cable.

Irregardless, it's just shady and aren't we tired of this?

why depopulate the MOV's for everywhere but Germany?
Although, Uni-T's 61010 test reports are quite a bit how ya doin' and the certifier could be glossing over the details.

Why bother with a plastic guard box around the fuse if you're only expecting 250V there? It makes no sense. I feel better when the meters have actually been tested to their rated 1,000V to prove the pcb clearances are correctly done.

Two disqualifiers
- numeric aspect ratio. sorry. only Fluke and HP get this right. these elongated characters are hard to read. disqualified
- non standard plug arrangement. prevents me from using things like 0.75 inch pitch bnc to banana adapters, thermocouple interfaces and so many other banana plugs on 0.75 pitch
eevblog multimeter has same issue . get those banana jacks in line. not all weirdo.

I'm pretty certain they are 0.75". All my 'weirdo' ones are, despite not being in a neat line.
They did some improvements what is really good , but it is still a bad meter . They sell it as an electricians meter , but it s definetively not . The CAT rating is still a lie , the fuses are only 250 V and do not have the rupture capacity they need for a proper CAT IV 600 V meter , the input protection is still lousy and the clearance is not good enough . Still many work to do for Uni-T :palm:Not much work needed: just replace the CAT rating with a realisting 250 V CAT 2 .

Definitely give the Aneng 870 a spin but get some of these super needle-sharp gold probes to go with it:
https://es.aliexpress.com/item/33006553337.html
A good (chinese) probe has resistance around 0.3 Ohm.
ProbeMaster around 0.25 Ohm
A good (chinese) probe has resistance around 0.3 Ohm.
ProbeMaster around 0.25 Ohm
I would expect about 10 times lower than that for good probes, i.e. around 30mOhm.
I have 2 pairs from 2 sellers, they are very sharp (good), but they oxide easily and the resistance is ~100 mOhm.
A good (chinese) probe has resistance around 30 mOhm.
ProbeMaster around 25 mOhm

but i want them in line... many pomona boxes and other 'adapters' bank on the 4 terminals to be either in line or in 'quad' (calibrators for example have ready wired blocks you simply plug in) . The key ones are the pitch between ground and Volt-ohm and ground-200mA range. for low current measurements you may want to use coax or triax cables and then you need a bnc or to banana adapter. in the old version at least the mA/uA range is next to COM , in the new version it is too far away. the 10A range sits next to COM .. FAIL !
But the big stinker is the aspect ratio of the numbers. They are too hard to read. Fluke has the ideal ratio becasue they copied it from HP's 7 segment displays. ( fluke is actually a smidgen wider than a HP 7 segment. Also the way the segments flow into one another ( the chamfered edges ) makes a big difference in readability. The numbers need to be designed just right when it comes to width , height , pitch and segment shape / angle. Fluke nailed it. So did HP. This elongated crap ? unreadable.free_electron, I suspect you would be surprised how similar the displays of various meters are these days. Check my page at:
Nice meter, though 20A DC measurement, with a 10A fuse...... Guess it is the same current shunt, just with the "30 seconds maximum" there to prevent you blowing the fuse too often.
Waiting for Joe to blow it up, and if it will survive the grill starter lowest energy test that he has. My bets are it might just barely pass, but will fail on the higher energy tests. But at least they spent the 30c and added in the 3 MOV's to it.
