What is the best multimeter?
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.
How to use a vom?
Definition: The multimeter or volt-ohm-milli-ammeter (VOM) is the type of meter which performs the multiple functions. In other words, in VOM the multiple measuring functions are combined in a single unit. The multimeter is used for measuring voltage, current and resistance.
What is volt-ohm-Milli-ammeter (vom)?
Mar 21, 2007 · A Volt-Ohm-Milliammeter, often called a multitester,can measure current on more than one scale. A voltage tester and a continuity tester are adequate for many diagnostic jobs, and they are relatively inexpensive. But for more serious electrical and appliance troubleshooting and repairs, invest in a volt-ohm-milliammeter, or volt-ohm meter (VOM). A VOM is battery …
What does vom mean on a meter?
commonCOM stands for common and is almost always connected to Ground or '-' of a circuit. The COM probe is conventionally black but there is no difference between the red probe and black probe other than color. 10A is the special port used when measuring large currents (greater than 200mA).
What is the use of VOM?
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.
How do you use a VOM meter?
Test Your Probes or LeadsSet your multimeter to the ohm meter on the selector knob.Plug the black probe into the common port.Insert the red probe into the jack marked for ohms.Gently tap the red and black tips together. ... Your reading should be 0.5 ohms or less.If your reading is higher than that, replace the probes.
What 3 things does a VOM meter measure?
A digital multimeter is a test tool used to measure two or more electrical values—principally voltage (volts), current (amps) and resistance (ohms).

Can a VOM measure AC current?
Both AC and DC currents can be measured with a multimeter by connecting the meter in series with the circuit, in which the current is measured provided the current in that circuit is limited or controlled by a load or appropriate values of resistance.Aug 25, 2021
Which meter will be most sensitive?
However, the moving-coil meter movement is used most often because it is more sensitive and more accurate. Although concentric-vane and radial-vane moving-iron meter movements can measure both ac and dc, they are generally used to measure low-frequency ac.Mar 17, 2018
How important is the multimeter Why?
The voltmeter, or more often the multimeter, is an incredible tool, capable of troubleshooting nearly every electrical system and fault in existence. No matter how often they are used, and what job they perform, there is always more you can accomplish with knowledge of how they work.May 8, 2020
What is a VOM meter?

What is a multimeter used for?
The multimeter is used for measuring voltage, current and resistance. It contains the circuitry switch which makes the meter to operate like a voltmeter, ammeter, and as an ohmmeter. Consider the circuit of the Simpsons multimeter.
Why is a VOM used?
A VOM is useful for testing appliances because it is used while the power is turned off, so there's no danger of electric shock. It provides more precise information than the continuity tester and, therefore, is preferable for testing many components.
What is a multi tester?
A multitester is used with plug-in test leads, which may have probes at both ends or a probe at one end and an alligator clip at the other. An adjustment knob or switch is set to measure current on the scale desired, usually ohms. The dial indicates the current flowing through the item being tested. Advertisement.
