Hello, I am using sapphire for peakforceQNM  calibration (multimode8, probe type: RTESPA).  Accoding to the <DRAFT:PeakForce QNM quick start guide> from Briker, the scale of force monitor has adjusted to 200mV. but the force curve I've got are quite diffrent from the curves from the guide: the adhision is much bigger than the max force value and the trace and retrace doesn't match. Could anyone please tell me how to solve this problem.

p.s. I have captured a screenshot but I don't know how to upload it.

Thank you
