Uni-T UT61E slowly returns to zero in all AC modes. Should I keep it or return?

I have an AN870, have never used it much, as it sits in a niche better served by my higher-end meters (unlike the more compact Aneng/Zoyi 8008/8009 formfactors that are quite handy for most portable/cheap meter uses cases). It also has a rather cheap quality feel for its size, which doesn't instill confidence when handling. But I see it referenced often as a big bang-for-buck meter with a purported accuracy and precision that rivals much more expensive meters. Seems suspect if what you say is true.

As far as I understood, Serg65536 didn't mean to say that AN870 doesn't give precise results, only that it calculates them by averaging and therefore you have to wait a little.
Right?

Waiting aside, I'm pretty sure an averaging of samples is by definition not going to be as precise as a real-time measurement. That's what I was saying, not that it wouldn't be still be adequate for many uses. Just as an averaging AC meter is still useful to those who don't require TRMS measurement.
