An prionsabal a thomhas toilleas le multimeter
Sa multimeter saor, déantar an tomhas toilleas a fháil trí am luchtaithe an toilleas tomhaiste a thiontú ina chuisle tríd an gciorcad bonn ama, an chuisle a chomhtháthú, agus ansin an luach comhtháite a thomhas.
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 comhshó.
