Regular price $ 3,966.67 CAD $ 4,117.61 CAD Sale

Measures insulation resistance to 10TΩ and features automatic calculation and presentation of the Dielectric Absorption Ratio (DAR), Polarization Index (PI) and Dielectric Discharge (DD).

Displays the test voltage, insulation resistance, and the leakage current during test. Capacitance of the sample and discharge voltage present at the test leads is displayed at the conclusion of the test. This meter is designed with the highest level of built-in safety features. Can be operated from an internal rechargeable battery system or from an AC line power.


  • Automatic voltage detection in all functions, before or during the measurement, which inhibits or stops the measurement
  • Automatic detection of external AC or DC voltages on the terminals
  • Threshold programming in each function, triggering audible alarms
  • Timed control of measurement duration
  • Fuse protection, with defective fuse detection and indication
  • Digital filtering of insulation measurements
  • Automatic discharge of residual high voltage on the tested device
  • Automatic shut-off to save the batteries
  • Battery level indicator
  • Large easy-to-read back-lit LCD

Test insulation on:

  • Cables
  • Transformers
  • Motors
  • Generators
  • Insulators
  • Wiring installations
