ABSTRACT:
A differential measurement probe has spring loaded, double cushioned probe assemblies and a pressure sensors disposed in a housing. The pressure sensors forms an electrical switch having an electrical AND function for passing an activation signal to a EOS/ESD protection control module in response to axial movement of the housing relative to the probe assemblies. First compressive elements produces first pre-loaded compressive forces and increasing compressive forces on the probe assemblies and second compressive elements produces second pre-loaded compressive forces and increasing compressive forces on the probe assemblies subsequent to the first increasing compressive forces on the probe assemblies. An adjustment member allows variable spacing of the differential probing tips.
