Karin,
To verify calibration, or re-calibrate, please see this document. The verification steps start on page 7. Information about calibration from National Instruments can be found at http://www.ni.com/support/calibrat/

Karin,
The document you have looked at is the best reference I can give. After this, I would suggest sending it in for calibration if you are receiving bad measurements.
