Dear Rene,
at present, calibration modules are designed to treat the uncertainties
namely - and 'C' means that uncertainty data are available
for these data (which can be seen when you e.g. run statistics
module or extract profiles). To perform simple recalibration
of your data I would choose Basic operations->Dimensions and units.
But you are right that the correction factors should be applied
within the calibration module as well, which is something that
needs to be fixed.
Best regards,
Petr

Live Security Virtual Conference
Exclusive live event will cover all the ways today's security and
threat landscape has changed and how IT managers can respond. Discussions
will include endpoint security, mobile security and the latest in malware
