Doesn't a mA seem high?

Especially when you consider the shunt resistance... take that out of circuit and it's going to be even higher.
Under constant observation the current leakage stabilized at 95μA maybe its the RTC and XTAL that's fine I guess...

As I said, mine will sit for months at a time and not discharge.
Another option, start with the grill starter, kill it in a few seconds and leave it at that.... Nice short video, right to the point.
Correct.
I mean, seriously, what is the point of testing the UT61E for "robustness"? We all know it isn't.At first glance yes. The UT61E (and probably the UT61E+) are finicky with transients but why not put it through its paces? Who knows? Perhaps it could be an additional advantage of the "plus" model...
Looking at the data I've collected, of the eight UNI-T products I looked at, half never made it past the ESD, AC line tests. During the EEVBLOG review for the 61E+, Dave focuses on the lack of a surge rated resistor. The UT181A is the same and survived some decent hits after a few small changes. Dave talks about the new ground path. It could help but my guess is it won't.Obviously that the "real" test would be with the "third party plus-certified and mega-accredited and über-listed" UT161E, but that is in another price league...
That meter would fail ESD just like the stripped down version.At any rate, I don't think there is much to be lost, especially after you already beaten to death the UT61E original, with excellent suggestions to increase its robustness.
For you, skim the video for a few seconds and your done. Flip side, it takes fair amount of my time to run the tests and edit the videos. For this meter, assuming the grill starter kills it, maybe six days. Half of that would be cycling the function switch.
(edit) Kerry Wong also did a teardown of the UT61E+

(edit2) Tenma has some discounts on beefed up UT61E (non plus)

Skimmed the Kerry Wong video but didn't notice anything beyond what Dave had gone over.
We could reorder the tests for this special meter. Start with the 100us transients. If it survives that (which it won't) then run the AC line test and then the ESD. Not sure we would learn anything more doing this. The end results the same.
UNI-T fanboys are already thinking I am biased against this meter. I can see the mass of down votes. lol. I have more than enough data now to know what to expect.
Hi,
I know this is reopening an old topic, but I would love to see how UT161E would fair in your tests.

Why? If robustness is a big concern then you can buy a proper multimeter for that much money.
And how does the warranty work on the UNI-T in the USA?
My other option is Brymen BM789 but I didnt want to spend that much and not sure how the warranty would even work on it, when its imported to US.
And how does the warranty work on the UNI-T in the USA?You can get warranty in the US for a "Uni-T like" by paying a steep premium from Farnell:

Terribly expensive for what it is. Even their old UT61E models do not have the promotional price anymore.

They don't have a BM789, but a BM869 instead. Paying a bit more than the originals, but it is the real deal. I just got a brand new DM200A (BM251S) on an eBay bargain (half of a UT61E+) and it is incredibly compact and well built, even features premium gold leads.
Got anything close to 161e feature wise, better protection around $100?
161E goes on sale for $56 at times, if you can recommend anything better that has same features or more I'm open to suggestions.
If not, would 161e be safe while working on 240v 3 phase machines?

No meter is 100% "safe" because there's always operator error. There's also a couple of pages now that are telling you that it's probably no better than the ordinary 61E, ie. the extra '1' in the name is mostly marketing.fluff to sell (practically) the same meter for more money.
The Fluke 101 is about as close as any meter gets to "safe" in untrained hands.
161 does have better fuses than 61E+.
I'm not a fan of carrying multiple multimeters
I wouldn't care much about 161e warranty for $50-60 price.

If not, would 161e be safe while working on 240v 3 phase machines? I would mod it to make it more robust but not electrical engineer, and I know it's not allowed to ask for help with that here sadly.
