EXAMPLES FROM CORPUS
▪
Voltmeter readings around IC2 should produce the following results, assuming that the negative lead of the voltmeter is connected to 0V.
▪
Calibration Select one amplifier for calibration and connect a voltmeter to the test point at the first stage output.
▪
Ideally, any alternating voltmeter should possess infinite impedance and any a.c. meter negligible impedance.
▪
Strictly speaking, the voltmeter should give true r.m.s. measurement.
▪
The r.m.s. current,, may be found by measuring the r.m.s. potential difference with a suitable voltmeter from which.
▪
This will change the voltage at any porthole whose current line is affected, and the appropriate voltmeter will register the fact.
