The CB101 calibration box is designed to verify the accuracy of insulation resistance testers. It contains four precision resistors that allow for testing across a broad range of resistance values. These high-voltage-rated resistors support measurements using test voltages up to 5 kV DC. Each CB101 unit comes with a calibration certificate detailing the exact resistance values at each checkpoint.
