What we calibrate

Handheld and bench insulation testers, megohmmeters, and high-voltage insulation test equipment. We verify output voltage, measurement accuracy, and safety interlocks.

Calibration procedure

  • Apply known high-voltage reference and measure insulation resistance across ranges.
  • Check polarization index (PI) and dielectric absorption ratio (DAR) where applicable.
  • Provide calibration certificate with uncertainty and environmental conditions.

Safety & notes

  • High-voltage testing requires trained personnel and proper PPE.
  • Discharge test objects after measurement to avoid stored charge hazards.
  • Follow manufacturer guidance for test leads and connections.
