The Sens Zsens parameter is the sensitivity of the Z scanner, expressed in nm/V. This parameter is fixed by the calibration of teh z scanner.

The problem we encounter is that this parameter is changing from images to images, altough no calibration has been performed in the meanwhile. Is this normal?

As this parameter is changing, we can not compare images, so would it be correct to go back to V using thet Sens Zsens for each images and then do the comparison? this not to throw away all our previous measurements.
