Hi
I pic UT71E at sunday market and play now. I see a lot of silly treads about CAT ratings :blah:
But what abouT accuracy and tolerance?
The main feature for me is TrueRMS AC+DC
Is it works adequate here?

30usd in trash. expensive piece of plastic. safe the planet and give it for recycling.

Which part of manual isn't clear to you?

Adequate for what?

manual says about fake CAT ratings
may be AC+DC mode is fake too, isnt it?

All is in specification. It is like many other cheap meters, useless for anything serious, useless for audio hobbyists, useless for electricians, maybe it can be ok for arduino players or checking accu voltage, or car battery.

So
did You have this meter?
Or that You can do is only hate everything, isnt it?

Accuracy and tolerance are ok, only the CAT ratings are more or less fake. There are different version of the PCB. Especially in Europe the chance to get a more secure version is given. E.g. my 71E has big HRC fuses what the international versions often don't have. But it was missing PTCs even it has places on the PCB for them. Concerning the quality of the routing on the PCB the European version is as bad as the international one. So if you know about these things the 71E is ok to use.

I have/had others till I decided no more this junk. Look at ac error above 1kHz and you will see how bad it is, see number of digits for error ... it is junk.

An optional additional explanation is:

There are several reviews on youtube. I believe they didn't have too many problems tolerance wise when new and can be manually calibrated. There are a few discussions on the forum here about calibration and upgrading safety.
Asking if a meter possibly 5 years old with an unknown history will still be as accurate is a coin toss. $30 USD is not too bad value wise, I would make an offer though. The meter came with a pouch, probes, temp probe, USB data cable, alligator clips.

This tread about UT71E not about "others" china meters
Don`t post here please since I have few words about "other" polish emigrants too 8)
And who the hell are you? Come back in a week and see if you can be more civil!

If such costs 30$, I would say good price/value.
Can't comment about tolerances but as already noted - refer to specs. Manufacturers as Uni-T usually do not lie there.

30$ really ? >:D I bought 4.5 metter (20 000 counts) for 10$ so eeeeeee really this 30$ seems to be way to high price for it

Accuracy is only a small part of the equation.
Those freebie DT830M meters are accurate but you wouldn't call them good meters.

There is a video out there somewhere of a guy pulling one along with a boat and later dragging it down the stairs with a rope. The meter survived just fine. Not bad for a free meter.
