Thank you for such a detailed review of the UNI-T UT8805E bench multimeter, very professional and useful!
for 400€ or so, that's amazing performance... it's crazy the world we live in these days. Yeah i'm old... :D
Thanks, I was considering one of these. The fan noise though... And it doesn't seem to be temperature dependent.

Yeah, the fan is unfortunately on the noisy side and is constantly on.
Hi! I appreciate your reviews. I also do reviews on Polish YT channel (Metrology). But I lacked information: what are the mathematical functions? What are the display modes? What is the actual measurement frequency (VM comp output)? How can you trigger a multimeter? Accuracy is not everything...

I tried to cover as much as I could in this video. If there are interests in these features I can demonstrate in a separate video.
They forgot to type one 0 (zero) in the AC BW spec.
is the input impedance also why the display on my hp 3457a jumps around when not being used? i always wondered why it did that. the manual said it was normal but didn't get into the why.

Stray electro magnetic fields, radio and all sorts things can induce voltage differentially in leads. Specially when there is a near open circuit at the meter. If you short the leads it will be dissipated as it has a path to balance it out. I have a 3478 myself with a very high input resistance/impedance and see the same.
good measurement considering its price. at 15m22s, 0.020nF=20 pico Farad ??
teardown! thanks
Teardown please!

It's coming!
Did you verify the input impedance? I think you would have shown what a mediocre instrument this is if you'd compared it's performance to the ut-61e+.
Durante la visualizzazione dei grafici, quando la memoria è piena il multimetro si inchioda e bisogna spegnerlo per sbloccarlo, che schifo. La gestione della reimpostazione manuale delle soglie di un grafico è orribile, non compratelo se dovete visualizzare grafici. L'autoscaling non esiste, quello manuale non funziona se la memoria è piena, che schifo. L'istogramma lo trovo inutilizzabile.
