The output can be interfaced with external equipment. A voltmeter is an instrument used for measuring electric potential difference between two points in an electric circuit.It is connected in parallel.It usually has a high resistance so that it takes a negligible current from the circuit. But analog meters do have one advantage: They are better at showing the rate of change of voltage with respect to time, which is useful when capacitance is involved. With time analog voltmeters are replaced by digital voltmeters due to the same advantages associated with digital systems.

Here are some advantages of digital multimeter. Analog Electronic Voltmeter; Digital Electronic Voltmeter; Analog Electronic Voltmeter – The meter whose output is obtained by the deflection of the pointer on the calibrated scale is known as the analogue electronic measurement. The LCD display makes the instrument user-friendly because usually analog multimeters are hard to read, but digital multimeters have LCD in them, providing a better view for the user. They are available in smaller sizes. All the parallax errors are eliminated by this instrument, and if the pointer of an analog multimeter is viewed from a different angle, you will see a different value. Disadvantages of having an error due to temperature decrease in sensitivity in AC operation. ResistanceThere are two types of multimeters commonly in use: 1. Every voltmeter or multimeter of analog type has internal resistance which is expressed in "Ohms/Volt". Most meters can do all three and have voltmeter, ohmmeter and ammeter features. Voltmeter is a voltage meter. in the market that it is extremely hard to find the one that suits your needs. … However, there are two distinct kinds of meters: analogue and digital. santhosh 8 years ago require more info about this.
