Dear Petr,
thank you very much for the response. I honestly think, that I missed
the feature you mentioned ('Basic operations->Dimensions and units').
This is actually a simple way to enter precisely the factors that I
mentioned in the first post.
Anyway, I think, it would be useful to implement those factors within
the calibration framework. So this would then be a feature request.
Thanks again. Keep up the great work!
Best regards,
Rene
