A reading near 0 Vdc points to a shorted line or connector fault.

As long as you match an 8 mm probe with an 8 mm extension cable and an 8 mm Proximitor sensor within the correct total loop length, the loop self-calibrates to factory specs.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eWhat shaft material is this probe factory-calibrated to measure?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe standard calibration target material is AISI 4140 electric steel.
