Frequently Asked Questions (FAQ)

• What is the main advantage of the NSv probe?
  • The 3300 NSv probe offers greater chemical resistance and better side-view characteristics than previous generations.
• Can I use this with my existing 3300 system?
  • Yes. It is mechanically and electrically interchangeable with 3300 RAM probes and cables.
• What if my target shaft is smaller than recommended?
  • For shafts under 13mm, you may need to reduce the gap setting to minimize scale factor changes.
