I have been talking to the author of DMM.
This seems to be our program :-+
You should be able to start two instances and connect two DMMs and each instance catches a DMM.
Each instance should then write its own logfile.
However, you will not get a single logfile with synched data. You have to do the sync after logging.
Well, that's ok for me.
Would be nice if somebody who owns two UT61E with USB interfaces could make a test ::)

Basic test with 2 UT71E: Works.
After startup of each instance, you can select between USB1 and USB2, and then display the data from the meter.
From the window you can select "Log to file" and then define a log file name for each window.
Trap for young players: Don't forget to activate "Send" on the UTs. Otherwise you might curse and search for a minute or so :palm:
Nice tool. Not beautiful, but it does its job.
btw: Tried the same with the UNI-T software v3.00, but with the original USB ports of my laptop:
Actually it works with two instances, but if you open the second window, both will log data from the same unit :-DD
Apparently, it's not intended to be used with identical meters...
Didix:
Perfect!
Looks that I need to order one more ...
Thanx fo testing !!

You're welcome!
Gern geschehen! :-+
I knew having two UTs might come handy one day :-DD
Another question:
Just took one of the UT71E apart. Although they are original Chinese, non-export versions, the PCB seems to be ready for upgrade with HRC fuses and additional MOVs (one is present, the other spots are unpopulated). I just can't recognize if the MOV spots have traces to them...
Is it worth to take care of these parts as a weekend project? :-/O

I don't have two UT61E, but I often connect my UT61E along with other devices also connected to the PC.
If all else failed....
The UT61E sends out data in standard 7 bit ASCII. (8 bit word but MSB is always zero). A TTY terminal emulation program will capture it nicely (and save/log to file.) So you can just start multiple instances of something like Hyperterminal and log the lines to file.
While it is feasible to capture different devices to different text files, it gets a little messy when the lines are not individually time stamp-ed. So, I found it easier to just write a Java program to grab the data from different ports (different devices) and log it to single file with PC's time stamp. I suppose you can write one with BASIC as well. My version of Basic supports only COM1 & COM2, so JAVA for me is easier and can use any COM port.
