Field Installation Guidelines
Install probe tip perpendicular to shaft surface for accurate displacement measurement.
Maintain insertion depth to achieve –10 VDC gap reference.
Route coaxial cable with shielding grounded at a single point to minimize interference.
Avoid sharp bends in cable to prevent conductor fatigue.
Confirm driver calibration after installation to ensure proper scaling.
