FAQ

• How do I confirm the probe sits in the linear zone?
• Measure gap voltage and compare it to expected values.
• Will temperature changes affect readings?
• Yes. Material expansion changes the gap slightly.
• Can other target metals work?
• Yes, but you must recalibrate for sensitivity differences.
• How should I route the cable?
• Keep the cable away from power conductors and motors.
• What causes long-term drift?
• Oil films, thermal cycling, and mechanical shifts cause drift.
