Uni-T UT890D, thoughts?

Admittedly, the other day I went to measure the AC mains input of my last DIY PSU with my old Mastech M92A in 10A amperimeter mode, you may guess what happened. :facepalm:

The probes' tips are a bit scorched now :-) and the multimeter still seems fine, but I've thought it may not be a bad idea to get a new one soon.

Budget's tight soo: https://www.aliexpress.com/item/UNI-T-UT890D-True-RMS-Measure-for-Current-and-Voltage-UT890D-REL-Function-for-Capacitance-Measuring/32801974582.html

Of course, the critter is discontinued and hasn't auto-range, but that's something I can live without given the rock bottom price. ;-)

Looks nice, doesn't it?

Working with main voltage, you need something safe
I recommend Fluke

I have this multimeter, if you only work with low voltage circuits, you may consider about it:

Cheers :beer:

Better get the 8008:

Tested by EEV-Blog - It’s very good for the price - but for Mains Voltage you won’t find a cheap but 100% safe DMM.

I think Barkuti will need temperature meter function of AN8002 more than signal generator function of AN8008.
By the way, I ordered one of AN8008 from Ebay and ít’s on the way …

So, I take it your AC mains can supply more than 10A? :smiley:

My AC mains stops somewhere at or above 20A, which is the rating of its mains switch. It's an old apartment (1980) and installation which originally had 15A via two switches (10A for the sockets and 5A for the lamps). Of course, such setup became obsolete as the gas stove and oven were retired, and more and more electrical appliances came into scene. As it is now, if I try to bake a pizza (2000W) while using my 900W compact electric fryer with the air conditioner on, lights and sheesh (the boiler is also electric) there's a good chance of tripping the electric meter's switch before the mains one. ;-)

It was the mains switch the one which tripped that day, so my bet is the meter briefly took 20+A.

Seen a video review & teardown in spanish (¿EL MEJOR TESTER? || TrueRMS y AutoRango || ANENG AN8002) about the Aneng AN8002. Juan, the review guy does a mention to Joe Smith's AN8008 review.

Surprisingly good meter, but Juan comments the 600V CAT III and 1000V CAT II high voltage ratings were more like 150V CAT III and 300V CAT II.

Honestly, do you believe my venerable Mastech M92A does it better? :facepalm:

Anyway, also looked here: UNI-T UT890D cheap accurate multimeter for very tight budgets @ EEVblog Electronics Community Forum

Auto range on capacitance and frequency.

Been my entire life without auto range, even used analog multimeters. To me, performance & features come first, don't really need auto shifting.

Actual protection for the UT890D looks as scarce as is for the AN8002. Should be enough for a peek or two at mains, though.

We'll see.
