Investigating the use of multimeters to measure high value capacitors at low frequencies against the quantized Hall resistance

摘要

Possibilities and limitations of using measurement system based on two sampling multimeters (DVM) for the ratio measurement of two impedances was investigated in MIKES. Calibration of a 1 µF capacitor from the quantized Hall resistance (QHR) was made at low frequencies. A frequency dependence of ceramic 1 µF capacitor in frequency range 12 Hz – 1600 Hz was measured against different reference resistors at low voltage level with the ratios of 1∶1 to 1∶100. A 1 µF capacitor can be measured at low frequency directly against the QHR by using precision DVM with proper estimation of applied corrections.
