This measurement tool is knowned as VOM (Volts, Ohms, Miliampere), although there are multimeters capable of measuring many other magnitudes as capacitance, frequency, temperature, etc.
 The multimeter because of its price and its accuracy, remains the favorite for amateur and for professionals in electronics. There are other instruments such as oscilloscope that is more expensive.
There are two types of multimeters: analog and digital.
The analog multimeter
The analog multimeters are easily identified by a needle that moves on a scale indicating the value of the measured quantity.
The digital Multimeter
 The digital multimeters are identified mainly by a numeric display in order to read the measured values.
Some of them have a scale selector and others do not. The scale is determined automatically on the multimeter that has no selector scale.
The function selector is used to select the type of measure that will be done.
For example:
The range selector is used to establish the maximum measurement value that we can display. If you do not have an idea of the magnitude you are going to measure, use the largest range. For example
Looking at the table above we can see that we always use a range higher than the magnitude being measured.
