An analog multimeter is a compact and portable instrument and therefore is very popularly used in practice. A multimeter is an instrument that is used for measuring various electrical properties such as voltage, resistance and the current in an electrical circuit. When the battery is low, the display will be dim, making reading difficult. These days DMMs are popularly used and they have almost entirely replaced analog multimeters. The name of the instrument itself suggests that a multimeter is used to measure more than one quantity. Find a resistor of known value. This is your one-stop encyclopedia that has numerous frequently asked questions answered. If a metre with a resistance sensitivity of a thousand ohms per volt would draw 1 milliampere or mA at full-scale voltage. Analogue voltmeters generally move their pointers across the scale with respect to the voltage a given electric circuit possesses. With the help of this transformer, currents up to 400A can be measured. An example of data being processed may be a unique identifier stored in a cookie. Lets discuss them in detail: The instrument we use to determine the potential electric difference between two points in an electric circuit is called a voltmeter. This article covers what are the different types of voltmeters which are being used. Digital Multimeter (DMM Meter) measures voltage using Analog to Digital Converter (ADC). A multimeter or a multitester, also known as a VOM (volt-ohm-milliammeter), is an electronic measuring instrument that combines several measurement functions in one unit. They reduce reading and interpolation errors.
