The calibration box has been designed to verify indications of insulation resistance meters. The use of high-quality resistors with a very high degree of accuracy makes the CS-5kV an ideal tool for cooperation with devices with a test voltage of up to 5 kV DC. The box enables the measurement of four resistance values and their combination. The device utilizes 4 mm banana plugs.


  • Nominal resistance values: 10 MΩ, 100 MΩ, 1 GΩ, 10 GΩ.
  • Fast verification of the correctness of insulation tester indications.
  • High accuracy reference resistors.
