Right. I'm connected to the instrument again and extracted some data. To start with what's working, I told the instrument to transfer the data in ascii format, read it with fscanf(g) and converted it using str2num. What you get then are the correct values and they look like this:

Fantastic!!! Can't wait to get back to work and try this out. Seems like fread is a trickier command than I first thought :)

Hmm, apparently there are different syntaxes depending on if you use fread for reading from a file or from an instrument.
