❓ Frequently Asked Questions

• Q1: Can I cut the probe cable to make it shorter?
  A: No. Cutting changes the 75Ω impedance and calibration. Order exact length you need.
• Q2: What happens if I over-torque the probe case?
  A: Over 7.3 N·m may strip threads or damage the internal coil. Always use torque wrench.
• Q3 (experience): My signal shows noise from a VFD. How to fix?
  A: Use shielded extension cable. Keep probe cable away from VFD cables (min 12 inches). Install ferrite cores near the proximitor.
• Q4 (purchasing guide): Warranty & shipping details?
  A: 12 months warranty. Ships 12-24 hours after order. Carriers: FedEx, UPS, DHL. Tracking provided.
• Q5 (buying tip): Which extension cable works with this probe?
  A: Use Bently Nevada 3300 series triaxial extension cables (330930-XX-XX). Keep total system length ≤9m (probe + extension).
