Description
CA-CCC is the calibration device of Capacitive Coupling Clamp (CCC), designed according to the latest international standards.
Calibration Setup:
Place the transducer plate inside the CCC, and align it with the bottom of the CCC. Connect the transducer plate with the low-impedance adaptor AD-CA-CCC then the 50 Ω attenuator. The adaptor ensures that the attenuator be properly connected to the reference ground, and holds the attenuator over 100 mm above the height of the CCC.
The distance between the transducer plate and the attenuator shall be less 0.1 m.
Calibration Process:
Calibration of the Capacitive Coupling Clamp is performed through setting of the open-circuit voltage of the EFT/B generator. The output voltage of the 50 Ω attenuator should be 1,000 V.
