Functions of a multimeter: A multimeter is used to make various electrical measurements, such as AC and DC voltage, AC and DC current, and resistance. It is called a multimeter because it combines the functions of a voltmeter, ammeter, and ohmmeter.
Multimeters may also have other functions, such as diode and continuity tests. A multimeter tests electrical continuity. It also can measure the amount of alternating current (AC or household current) or direct current (DC or battery current) in a plugged-in or live circuit. It can check voltage, too.
A multimeter is a very valuable diagnostic tool. With engine management systems being electronic it is one of the most powerful and versatile tools. With a good wiring diagram and a good multimeter, you can find the cause of almost any problem be it electrical or electronic.There are two basic types of multimeters, digital and analog. Analog multimeters have a needle and the digital has an LCD or a LED display..
