Hello,
I edited the first message. added pictures again. imageshack f.ed up my acount.
I am proud of this topic. :D
I dont know if it is mentioned before i realized that you can keep the dmm always in display check (all segments lighting up) mode.
If you push and hold "HOLD" button while cranking the knob to any range and wait for 4 sec. to relaese the hold button it will stay in display check mode until you press the hold button again or restart the dmm.

It seems they didn't piggyback the capacitors.

Where can we find a full/complete API description?
Has it been made publicly available as PDF or HTML download?

In Nov 2016, I had measured the temperature drift of my new UT61E and made a video were I compensated it. I had also changed out the one trimmer pot. Someone had asked about long term drift and I mentioned I would start collecting some data from mine. It sounds like some people are seeing a lot of drift. I can't help but wonder if this is operator or the meter.
Anyway, here is some data from my UT61E after the temperature compensation taken on 11-21-16:
1mV: 1.02
1V: 1.0001
10V: 10.002
1nF: 1.003
I have had the meter apart a few times since then to make other modifications to it including the larger shunt for measuring 20A and attempting to improve the burden voltage in the uA range. However, I have been careful not to adjust the trimmers that would effect this little study.
You can see the in the mV range the meter appears to have a change of 30uV. However, it's way to small of a change to hang my hat on and way too little time has passed. I would expect the meter would be fairly stable. Maybe people are using an unstable source to look at drift?

Hi guys, i am not sure if this piece of interesting information is known. It was news to me:
There is yet another PC logging software which has official (commercial) support for UT61E. It is developed by geman compani called ABACOM , and it is sold through various renowned geman electronics retailers. The software is called
ABACOM REALVIEW 3.0
You can download the latest Update (from 2015 afaik) for free from:
http://www.abacom-online.de/html/downloads.html
It is pretty good and advanced, more professional than ultradmm.com . Please share in this thread which logging software you like best for UT61E. Either software does the job and delivers an exported data file which can be imported to Excel. So it doesn't really matter which software one uses for the logging and real-time plotting. It is matter of taste and preference.
With Realview 3.0 you got a very serious piece of software, professional and commercial. If you don't like freeware.
