Audio Millivoltmeter. When performing any tests on an audio system, some form of measuring device is essential. Digital multimeters are not useful, since they will not give the true picture of what is happening, and most have a fairly limited frequency range. An oscilloscope is the ideal tool, but not all hobbyists can afford the outlay for a ...

For audio- frequency power measurement a rectifier type voltmeter will be used choosing proper diodes for the rectifier that offer minimum capacitance. A standard resistance of 600 ohm will be taken and the rectifier type voltmeter will be connected across it. When 1 W of power is dissipated across this resistance the voltmeter reads 0.775 V.
