Načelo merjenja kapacitivnosti z multimetrom


V poceni multimetru se meritev kapacitivnosti pridobi s pretvorbo časa polnjenja izmerjene kapacitivnosti v impulz skozi vezje časovne osnove, integracijo impulza in nato merjenje integrirane vrednosti.

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 ->V pretvorba.
