I calibrated the tip in ramp mode on clean hard surface first and then used it for imageing. I got DMT modulus mapping range from negative values to positive ones such as -2 MPa to 5 MPa. Any one knows why this is happening? Is this DMT modulus mapping result meaningful at all? Thanks!

How does the software know that the tip radius changes when the tip is worn or contaminated during the scanning? In addition, How does the software know the tip radius for different tips?
