So, finally some answers, but not one of them are good.

Fluke told me they didn't have anything except the users manual (which is wrong as they host for of the manuals on their servers) and that thay didn't have the software needed for calibration. They didn't know anything about someone in Germany who had the software nor anyone who could calibrate them. Strange answer I think.

Nor does any of the Swedish calibration centers offer calibration and only one knows of the German calibration possibility - I am still waiting for an offer from Germany via the Swedish calibration center.
