Apparatus and methods for determining force applied to the tip of a probe

An apparatus for determining a force F.sub.tip applied to a tip of an electrical impedance spectroscopy probe includes a load cell, accelerometer, and a processing means. The probe tip has a substantially planar distal end for contacting human or animal tissue. The load cell measures the force F.sub.loadcell applied axially along a longitudinal axis when the probe tip is in contact with human or animal tissue. The accelerometer measures a gravity vector A.sub.axial. The apparatus includes a means for compensating for the mass of the probe tip using the measured force and the gravity vector to produce a calibrated measurement force F applied to the probe tip.
