Prinsip mengukur kapasiti dengan multimeter


Dalam multimeter murah, ukuran kapasitansi diperoleh dengan menukar masa pengecasan kapasitans yang diukur menjadi nadi melalui litar asas masa, menyepadukan nadi, dan kemudian mengukur nilai bersepadu.

Slightly better may use quadrature detection, that is, the so-called digital bridge, after measuring the phase difference, use the single-chip microcomputer to calculate the result of the reactance. In addition, the frequency method can also be used to measure the capacitance through the frequency change of the oscillation circuit. C diff -> Freq Diff frequency change can be measured with a counter, or read out with a voltmeter for F ->penukaran V.
