What is a multimeter?

A multimeter denotes either a hand-held device which is useful for finding basic faults, or a bench instrument which can measure to highly specific degrees of accuracy. Multimeters can be used to identify electrical problems in a range of industrial and household devices, whether it’s electronic equipment, motor controls, domestic appliances, power supplies or wiring.

Most modern multimeters are digital, enabling you to get a clearer reading from your piece of equipment or appliance. However, if you wish, you can still purchase analogue multimeters with moving pointers: these are particularly useful if you wish to monitor a rapidly varying value.

What do they measure?

Multimeters are often known as VOMs, or volt-ohm-milliammeters. This is because they tend to have several measurement functions, including the ability to measure voltage, current and resistance.

Many modern models also have additional functions, such as the ability to check fuses and batteries and measure temperatures.

Directions for use

Most multimeters have three distinct parts, or controls. These are the display screen, which often takes up the large majority of the surface area. You then have the probe, which connects to whatever it is you want to measure. There are often two probes, and they are usually red and black in colour. You then have the rotatory knob, which you use to select the quantity you’re measuring.
