If the I-V measurement data is saturated as shown in the figure below, decrease the gain
specified for Preamp Gain on the SPS Parameters window.
Decrease the value in Preamp Gain of the SPS Parameters window.
If no stable data is obtained at the same measu rement point or unreasonable data is
obtained, the cantilever might be irregularly bent due to an electrostatic force during
the measurement. In such a case, try to reduce the I-V scanning voltage range.
