Abstract: The disclosure relates to the field of measurement and calibration of capacitance, especially the instrument of transferring capacitance. A wide range capacitor standard box comprises a chassis, 36 physical capacitors, and 4 changeover switches. Output ports are on the front panel of the chassis. 4 dial-switches select the output capacitance in values of 1, 2, 5 times of single-unit capacitance. The changeover switch has input terminals that connect to two electrodes of the physical capacitors, and output terminals that connect to the output ports. Comparing to decade capacitor standard boxes, the present box realizes capacitance outputs from 1 pF˜500 mF in values of 1, 2, 5 times of single-unit capacitance. The present box significantly extends the measurement range of capacitance, and makes the capacitor standard box smaller and lighter. By introducing a compensation function for open and short circuits, it is convenient and suitable for precision measurement.
