During commissioning, installers must perform gap voltage validation to confirm a -10 VDC target, which ensures the device is operating at the center of its linear range for optimal fidelity in rotor dynamics observation. In configurations utilizing multiple sensors, cross-talk suppression is achieved by maintaining strictly defined spacing between adjacent probe tips, preventing inductive interference within the oscillator circuit.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Is it permissible to field-modify the 9.0 meter coaxial cable length?\u003c\/p\u003e\n\u003cp\u003eA: No. The 3300 XL Proximitor system is factory-calibrated as an integrated assembly (probe, extension cable, and Proximitor).
