content: HiI pic UT71E at sunday market and play now. I see a lot of silly treads about CAT ratingsBut what abouT accuracy and tolerance?The main feature for me is TrueRMS AC+DCIs it works adequate here?

content: 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.

content: 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.

content: 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.

content: Review :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.

content: 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.
