What is a volt ohm Milliammeter?
[′vōlt ′ōm ¦mil·ē′am‚ēd·ər] (engineering) A test instrument having a number of different ranges for measuring voltage, current, and resistance. Also known as circuit analyzer; multimeter; multiple-purpose tester.
What is use of volt ohm Milliammeter?
A VOM is battery powered and is used with the current turned off. It’s used to check continuity in a wire or component and to measure the electrical current — from 0 to 250 volts, AC (alternating current, as in houses) or DC (direct current, as in batteries) — flowing through the wire or component.
What are the types of VOM?
Types of Multimeter
- Analog Multimeter.
- Digital Multimeter.
- Fluke Multimeter.
- Clamp Type.
- Autoranging Type.
What does a Milliammeter do?
an instrument for measuring small electric currents, calibrated in milliamperes.
What is the function of Milliammeter?
noun In electricity, an instrument for the measurement of small electric currents, in which the scale is graduated to read in thousandths of an ampere.
Why is volt-ohm-Milliammeter invented?
Definition: A common and simple multimeter used in electronic circuits is the volt-ohm-milliammeter or VOM. When an electronic device called a field-effect transistor was developed, a VOM was designed to overcome the low input impedance problem.
What is the unit of Milliammeter?
noun. an instrument for measuring small electric currents, calibrated in milliamperes.
What is the classification of Volt Ohm Milliammeter?
Definition: A common and simple multimeter used in electronic circuits is the volt-ohm-milliammeter or VOM. A VOM is a voltmeter, ammeter, and ohmmeter, all in one. The VOM has the advantages of being inexpensive and portable.
What is multimeter physics?
A multimeter or a multitester, also known as a volt/ohm meter or VOM, is an electronic measuring instrument that combines several measurement functions in one unit. A typical multimeter may include features such as the ability to measure voltage, current and resistance.
