Which version of the UT61E software did you try: v2 or v4?

Did you already try DMM (https://www-user.tu-chemnitz.de/~heha/hs/UNI-T/ )?
From the infos on that page it is not clear whether you can log two UT61E or not.

*UT71E  ;)
I have two identical (with succeeding serial numbers, so same batch I suppose) UT71E, directly bought in China.

First, I used the software, which I downloaded earlier. It's v2.00, IIRC.
Second go, I used the current software v3.00.

edit: Both ways didn't work.
I'll have to check with my laptop, using USB ports without a hub.
Maybe tomorrow or next weekend, as I'll be away in between.

I didn't yet try the DMM software you linked.
I'll check it a.s.a.p.  :-+

Didix:
Yes, sorry, I have overseen that you have two UT71E.

I ask myself, whether it matters, what software you take. They look all the same and DMM seems to talk to all Uni-Ts.

However, to put the question again into the ring: does anybody have two UT61E?

I'll never give up!  8)

Thilo78:
I'm not perfectly sure, if the type matters if both meters are the same.
But it occurred to me, that it works if you have two different meters. Maybe the USB identifier is different between UT71E and UT71D or other combination....    :-//

Let me try, if I can manage to hook up the two UT71E by using direct USB connection.

The GS version has better input protection but has a lower CAT rating. The information is here on the forum somewhere and in this thread I think.

After having both the UT61E and the UT139C I recommend the UT139C instead, if you don't need the PC connection.

OK maybe there are really some different versions on the market with different certifications and cat ratings . Maybe this would be the reason of the price here in Europe . They let pay the GS certification by the german customers for lowering the cat ratings . Crazy business  :-DD

This is the German GS version:

crystal: Interesting. So it differs from Chinese version with 4 MOVs and bigger fuse holders - https://www.eevblog.com/forum/testgear/uni-t-ut61e-multimeter-teardown-photos/msg545943/#msg545943 (Also, there is missing VR5 calibration resistor for 10A range on that GS version).

So what's fuse voltage rating and type of MOV used in GS version?
