Fig. 2 shows the circuit of thedigital voltmeter. The voltage to bemeasured is applied across points ‘INL’and ‘IN-H’ of pins 30 and 31 of IC1,respectively, through circuit resistorsR5, R6, R7 or R8 and preset VR1.Resistor R2 together with C5 formsthe circuit used to set the frequency ofthe oscillator (clock), which is set at 48kHz approximately. At this clock rate,there are about three different readingsper second.Capacitor C4, which is connectedbetween pins 33 and 34 of IC1, compensatesfor the error caused by theinternal reference voltage and alsokeeps the display steady.

Normally ac voltmeters are average responding type and the meter is calibrated in terms of the rms values for a sine wave. Since most of the voltage measurements involve sinusoidal waveform so this method of measuring rms value of ac voltages works satisfactorily and is less expensive than true rms respond­ing voltmeters. However, in case of measurement of non-sinusoidal waveform voltage, this meter will give high or low reading depending on the form factor of the waveform of the voltage to be measured.
Analog multimeters are electrical test instruments ..................[:=> Show Contents <=:]

have a constant input resistance of 10 megohms regardless of set measurement range.
Digital voltmeters (DVMs) are now the preferred instruments for ac and dc measurements at all levels of accuracy and at all voltages up to 1 kV. Essentially a digital voltmeter consists of a voltage reference, usually provided by a Zener diode, an analog-to-digital converter and digital display system, and a power supply, which may be derived from either the mains or a battery. The basic range of the instrument provides measurement from zero to 10 or 20 V. Additional lower ranges may be provided by amplifiers,..................[:=> Show Contents <=:]
