- 1. Multimeter A Multimeter is an electronic instrument, every electronic technician and engineers widely used piece of test equipment. Multimeter is mainly used to measure the three basic electrical characteristics of voltage, current and resistance. It can also be used to test continuity between two points in a electrical circuit https://www.google.co.in/url?sa=i&rct=j&q=&esrc=s&source=imgres&cd=&cad=rja&uact=8&ved=0ahUKEwi- 9uDAi9HSAhWFHJQKHd57B- QQjRwIBw&url=https%3A%2F%2Fen.wikipedia.org%2Fwiki%2FMultimeter&psig=AFQjCNF1UxhNR06crpQEf-fw- iWhaERxCQ&ust=1489412345755276
- 2. APPLICATION: The applications of ammeter mainly involves in various electrical and electronic projects for the purpose of components testing and also used in different measurement applications in multimeter. •Temperature and Environmental Applications Low cost weather station DMM internal temperature •Voltage Measurements High and low value DC measurement Peak to Peak and DC average measurement •Current Measurements DC current measurement True RMS AC current
- 3. •Resistance Measurement micro ohm meter Measuring resistance with constant voltage Measuring resistance with constant current •Time and Frequency measurement Fast frequency Time measurement TYPES OF MULTIMETER: There are different types of multimeter like Analog, Digital and Fluke multimeters.

- 4. Analog Multimeter: The Analog Multimeter or VOM (Volt-Ohm-Milliammeter) is constructed using a moving coil meter and a pointer to indicate the reading on the scale. https://www.elprocus.com/wp-content/uploads/2013/04/Analog-Multimeter.png Fluke Multimeter: The fluke multimeters are protected against the transient voltage. It is a small portable device used to measure voltage, current and test diodes.
- 5. ADVANTAGES AND DISADVANTAGES OF MULTIMETERS DIGITAL MULTIMETER: Advantages of a Digital Multi meter are its output display which directly shows the measured value, high accuracy, ability to read both positive and negative values. ANALOG MULTIMETER: Advantages of an Analog Multi meter are that it is inexpensive, doesn’t require a battery, can measure fluctuations in the readings
