Digital Voltmeters (DVMs)
Points : Digital Voltmeters (DVMs), Definition
A digital voltmeter (DVM) displays the value of a.c or d.c voltages being measured directly as discrete numerical
in the decimal number system. Numerical readout of DVMs is advantageous since it eliminates observational errors
committed by operations. The errors ob account of parallax and approximations are entirely eliminated. The use of
digital voltmeters increases the speed with which readings can be taken. Also the output of digital voltmeters can
be fed to memory devices for storage and future computations.
A digital voltmeters is a versatile and accurate voltmeter which has many Laboratory applications. On account of
developments in the integrated circuit (ICO technology, it has been possible to reduce the size, power
requirements, and cost of digital voltmeters. In fact for the same accuracy, a digital voltmeter now is less
costly then its analog counterpart. Due to small size of DVMs the portability of the
instruments has increased.
