Thanks HighVoltage, you have spotted LA7SJA problem.
It turns out that 34461A does not accept the FORM:DATA command while both 34465A and 34470A does.
I'll look for a solution and let you know.

LA7SJA:
I just sent you a link to my export csv file, the file is seemingly correct (Measuring a 5V ref.) but the program only read 0 (zero) even when reading back the export file.

Attached the new version with the FORM:DATA removed for the 34461A limitation.

It's strange, I can open your file and display a graph without problems. If this update doesn't fix the problem we'll continue tomorrow.

Best,

LA7SJA:
If I change the region to Netherland it sort of works but it shows volts 4999... and not +4.999. This smells like C# automagic import number string Voodoo. Sorry if I can't help you any more but you should be able to change region to Norway or Sweden..... and test. There are many undocumented "features" in the C# metodes that uses the Region/Language settings when converting numbers to strings and strings to numbers and even reading .csv files I m used to write my own import, export and conversion rutines.

HKJ:
Is that the usual problem with decimal separator that is either , or . depending on country. If the program makes CSV files it also has to be aware of the windows delimiter settings that is , or ; depending on country.
