Talpos matavimo multimetru principas
Pigiame multimetre talpos matavimas gaunamas konvertuojant išmatuotos talpos įkrovimo laiką į impulsą per laiko bazinę grandinę, integruojant impulsą ir išmatuojant integruotą vertę.
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 konversija.
