Hi!
As promised, here are the measurements.
Not written in a neat excel font, but on old school paper.
I have perform the tests with a 34401A and a Keithley 199. These meters are well known amongst you.
The picture shows how the measurements were performed.
As you can see on the paper, in the low ranges there is overall a 0.040mV deviation. But if you look at the "0" range, you can see that there was -0.040mV measured.
So overall the readings seems right with that, that was selected.
Next to the binary ranges, i also measured the last 4 other ranges from the max 10000mV range.
Overall i am very satisfied with it.
I have compared the two meters, but you'll all know what they say about a man with two watches!
I hope that someone perhaps have some schematics for me..
Kind regards,
Christiaan
