Thome thoughts..
OFFTOPIC:
-MS8911
Some years ago the ELEKTOR magazine declared it to an absolutely must have for every hobbyist, nowadays they switched over to DT71.
Some german bloggers recommended the Mastech, too. And still remain.
Other bloggers proclaimed HP4070 and last year I was willing to order one.
But on some easteuropean and (esp.) russian forum I learned actual HP4070 = HP990C, no more hacking, accuracy no more 1%...
So I went out to find some info about DT71.
And I found some interesting stuff, especially a comparison of DT71 with UT116C.
Result: Depending on the scope sometimes one outperforms the other and vice versa.
All in all the DT71 is quicker and more accurate but it lacks sometimes at capacities and LEDs.
So I decided to order an UT 4 months ago but some sort of virus made the journey very long.

BTW... SMD testers are TESTERs and no high precision measurement instruments
ONTOPIC:
I ordered a 4wire DL24 on Ali's 11.11 SALE and it arrived last year and is still lying in the edge due to custums stress with batteries.
I bought it for capacity test with selfwelded battery packs, 10s and 13s.
The manual tells:
Test voltage 150V, working current 20A.
On russian forum I learned:
Never ever more than 150V! (no prob for me)
10A max, absolutely!
Looking at the traces I guess its right, 20A seem to be utopic.
