Digital Multimeter
A multimeter, also called a volt-ohm meter or VOM, is a device that measures resistance, voltage and current in electronic circuits. Some also test diodes and continuity. Multimeters are small, lightweight and battery operated, and they can test a wide variety of electronic components in many situations, making them indispensable tools for anyone who needs to test and repair electronic circuits.
A digital multimeter is a instrument which is used to measure voltage, current, resistance also it can measures frequency and periodic waveforms. It manly used as test equipement, for example if you had created a circuit you can use it to see if there a fault so then it can be corrected.
