Working of true rms reading voltmeter
There are two thermocouples namely measuring thermocouple and balancing thermocouple. They forms a part of bridge at the input of DC amplifier. The same non linearity effect takes place in both the thermocouple, so this effect is compensated.
Construction of average responding voltmeter
The basic construction of average responding voltmeter is shown in above fig. at the input side of an unknown voltage to be measured is applied. The blocking capacitor is used to block dc signals entering into the
Advantages and disadvantages of true RMS reading voltmeter
There are some advantages of true RMS reading voltmeter which are given below, The true RMS value is measured independently of an input signal waveform. Because of the use of two thermocouples, the non linearity problem is
