Frequently Asked Questions

• What does reverse mount mean?
  • Probe installs behind the target surface.
  • Ideal when front mounting space is not available.
• How to verify probe is functioning correctly?
  • Measure center to outer conductor resistance.
  • Should read 5.9 ± 0.5 ohms at room temperature.
• Signal drops intermittently. What to check?
  • Tighten ClickLoc connector finger tight plus 1/8 turn.
  • Inspect extension cable for damage.
  • Check for loose connections in the signal chain.
• Can this probe be used in Zone 0 areas?
  • Yes, with ia approval and proper zener barriers.
  • Follow Bently Nevada drawing 141092 for installation.
• How to select the right probe length?
  • Choose 1.0 meter for short cable runs near monitor.
  • Select 5 or 9 meters for remote mounting.
