Hi, Joe! Serial number of my S7081 is 000236 - one of the first models, that lack of some minor improvements in the Input Amplifier and DC/AC Ranging. I'm using a simple freeware serial port terminal emulation program "Terminal v1.9b" https://sites.google.com/site/terminalbpp/ I'm save all the output to a log file, cut out the header and ending, then rename it to "CSV" standart EXCEL extention. That's all! Mickle

Mickle, ' I got the emulation program, figured out how to make it work ('Custom' baud rate and '300' in the space below) and was able to save a file. Now to get Excel on my shop computer and figure out how to turn data into a graph. Just shorting my leads and watching, it is somewhat variable but primarily 0.000 000 00 +/- 2 to 3 uV on the 0.1 V scale. Seems a bit noisy but I have no experience with meters this sensitive. I also have an issue with the front panel connector that I think is just wear and tear on the connector. I have ordered a replacement but it will not be here for several weeks. When I install it, should I use silver solder? Or is just attention to detail when it comes to removing the flux the main issue?

The solder with the lowest seebeck effect is solder containing some cadmium, not easy to get hold of, otherwise they are all similar. > From: jltran@att.net > To: timka2k@yandex.ru; volt-nuts@febo.com > Date: Mon, 12 Sep 2011 07:49:08 -0500 > Subject: Re: [volt-nuts] [Bulk] Re: Solartron 7081 noise > > Mickle, > ' > I got the emulation program, figured out how to make it work ('Custom' baud > rate and '300' in the space below) and was able to save a file.

Just walked into the shop and the meter was on all day with the input shorted via my 'home made' test lead set. It was incredibly stable sitting at about 1.5 uV +/- about 0.05 uV. Perhaps leaving it on for the duration is having a beneficial effect at driving out moisture or other contaminants. Now the question is whether or not it would remain stable after turning it off for a week or two then turning it back on.
