A multimeter is an electrical meter that has multiple functions. Also called a volt-ohm meter (VOM), it can measure the following parameters:
- Voltage
- Current
- Resistance
There are different types of multimeters with different accuracy ranges. They can be either analog or digital and can come in either handheld form (see Figure 22.11 below) or as a bulky appliance. Multimeters generally do not require any kind of training and are relatively easy to use.
