What is an analog voltmeter?
Analog voltmeter is a move pointer across a scale in proportion to the voltage of the circuit.
What is a digital voltmeter?
With the time an analog voltmeter is replaced by digital voltmeter due to the same advantages associated with digital systems. Digital voltmeter gives a numerical display of voltage by the help of an analog to digital converter.
The main comparison between analog voltmeter and a digital voltmeter is that digital voltmeter electronically displays results on an LCD screen while in we are using analog voltmeter gives the reading by moving a needle across a printed background of possible results.
The main key difference between analog voltmeter and digital voltmeter are listed below:
- In Digital voltmeter the output signal is represented in the form of digital. While in analog voltmeter the output signal representation is done by using potentiometric deflection.
- Digital voltmeter is two types: Ramp type and integrated type while in analog voltmeter are three types: Average reading, true RMS reading, sampling type, etc.
- Digital voltmeter has an overload indication, an analog voltmeter has no overload indication in analog voltmeter.
- In a digital voltmeter has better resolution compared to an analog voltmeter.
- A digital voltmeter can be programmed, Analog voltmeter cannot be programmed.
- Sensitivity is more in digital voltmeter compare to an analog voltmeter.
- Digital voltmeter has a speed of operation is more Burt in analog voltmeter the speed of operation is less.
- While we are using digital voltmeter the digitization of signal is required while in analog voltmeter is not require digitization of signal.
- The more number of measurement range while using digital voltmeter compared to an analog voltmeter.
In this theory, we have to discuss the difference between an analog voltmeter and a digital voltmeter. I hope by reading this article you have to gain some basic information about this article.
