Abstract
A drive actuator for a measurement instrument having a probe, the drive actuator including a heating element in a thermally conductive relationship with the probe such that application of electric current to the heating element modifies a characteristic of the probe. The probe device includes a probe including a cantilever having a lever made of a material having a selected thermal expansivity and a drive actuator in operable cooperation with the cantilever lever made of a material having a thermal expansivity different than the thermal expansivity of the material of which the cantilever lever is made.
