FAQ

Typically, such insulation testers should be calibrated annually (every 12 months) to ensure accurate measurement and meet industry compliance standards. User environment and regulations might mandate shorter calibration intervals.

You should calibrate the tester if:
- It has been a year (or the manufacturer/relevant regulation's recommended interval) since the last calibration.
- It has experienced any physical shock, damage, or exposure to extreme conditions.
- The readings are inconsistent or outside the expected range when measured against a known standard.
- Internal checks or self-tests (if available) indicate calibration is needed.
- Prior to critical or compliance-based testing events.---
