Aiming at the technical problems of complicated calibration procedures,high maintenance costs,and excessive errors faced when using capacitors and reactors to calibrate capacitance-inductance testers,a new capacitance-inductance tester calibration device is designed in this paper.The calibration device includes a gear automatic switching module,an output proportional control module,a phase shift switching module,a current amplification adjustment module,and a control module,which realizes the traceability of standard values by converting the capacitance and inductance values to be measured by the tester into the phase relationship of voltage and current.In this design,the standard value is divided into seven steps according to the current output range and automatically switched between the steps,which can effective- ly improve the calibration accuracy.The experimental test results show that the stability of the output current of the cur- rent amplification adjustment module can reach the order of 10-⁴,and the measurement uncertainties of the standard val- ues of capacitanceand inductance at 2 and 20 Vinput voltages are evaluated separately,and the relative expansion uncer- tainties of the calibration inductance and capacitance are better than 0.15%,which proves that the measurement uncer- tainties meet the design requirements.
