names. Some people call them as “multimeter” or just “meter”, while
others refer them as “VOMs” or “multitesters”or even “tester”. They are
among the simplest and least expensive pieces of test equipment available
that every electronic enthusiast should have.

A multimeter is as basic to an electronic technician as a brush is to a
painter. In this chapter, you will learn the features of analogue and digital
multimeter and in the following chapters you will learn how to measure
electrical voltage, current, and resistance. Learning how to connect a
meter and read these electrical circuit values is a fundamental skill that
every electronics repairers must know in order to successfully perform
basic tests, troubleshooting and repairing.

Meter’s Function and Range

Analogue and digital multimeters have either a rotary selector switch or
push buttons to select the appropriate function and range. Some Digital
Multimeter (DMMs) are auto ranging; they automatically select the
correct range of voltage, resistance, or current when doing a test.
However you still need to select the function.
