Multimetr bilan sig'imni o'lchash printsipi
Arzon multimetrda sig'im o'lchovi o'lchangan sig'imning zaryadlash vaqtini vaqt bazasi sxemasi orqali impulsga aylantirish, impulsni birlashtirish va keyin integral qiymatni o'lchash yo'li bilan olinadi.
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 konvertatsiya.
