Abstract： To solve the traceability issue of the current indication error parameters of the medical leakage current tester， a calibration device for the medical leakage current tester has been developed. This article introduces the research plan and hardware implementation of the calibration device. Then， the performance of the calibration device is verified through a series of experiments， and finally， the traceability method for the current indication error parameters of the medical leakage current tester is determined.
