Remote calibration system for standard inductors of 10 mH has been developed. At the National Metrology Institute of Japan (NMIJ), the calibration of inductors which is traceable to the national standards is provided to clients, only if their devices under test (DUTs), i.e. their own inductors, are carried by themselves to the NMIJ. On the contrary, the remote calibration method enables the clients' inductors to be calibrated without being carried to the NMIJ. The calibration capability of the developed system for the remote calibration was evaluated to be the relative standard uncertainty of about 20 parts per million (ppm), in the case of the calibration of 10 mH standard inductors. From the verification test of this method for three clients in Japan, the results by the remote calibration agreed with those by the conventional method within the standard uncertainties.
