ITC8 Resistor Calibration Box


ITC8 Insulation Tester Checker is designed to check calibration of resistance ranges of insulation testers and multimeters. it is also used to verify insulation testers and multimeters.

By checking an instrument regularly against known resistances it allows the user to verify that measurements taken are accurate (within the tolerances of the instrument and then check box).



  • 12 Resistance Ranges (Ω): 0.5Ω. 1Ω. 2Ω. 20Ω. 200Ω. 1kΩ. 10kΩ. 20kΩ. 100kΩ. 1MΩ. 2MΩ. 10MΩ.
  • Accuracy 0.5Ω - 2Ω: ± 0.05Ω.
