Precautions while using Cathode Ray Oscilloscope
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 andcontinuity tests. The descriptions and pictures that follow are specific to the Fluke 73 Series III Multimeter, but other multimeters are similar.
