What are the Functions of a Multimeter?

When they were just starting to be used, multimeters were designed to measure voltage, current, and resistance. Over the years, however, they have become easier and more accurate to use while at the same time be able to measure a lot of different electrical components.

Let’s have a look at What are the Functions of a Multimeter , shall we?

What are the Functions of a Multimeter

Voltage measurement.

Voltage is simply the electrical potential of a circuit and most multimeters should be able to measure this perfectly. Taking the voltage readings on an auto-ranging multimeter and a manual ranging one is done differently. Depending on the type of meter you have, you should know how to take the voltage reading perfectly.

Current measurement.

Besides voltage, a perfectly-working multimeter should take the current reading quite well. When it comes to measuring current, you should have the multimeter connected to the circuit or component in series. If you’re using a manual ranging one, ensure that you set the dial to either DC or AC.

Continuity.

This is simply the check of whether or not the circuit is flawed. Continuity measurement is done with the dial set in the continuity range. The probes, on the other hand, are connected to the meter just as you would connect them when measuring voltage

Diode continuity

A diode is an electronic component that allows current to flow only in one direction. To check for diode continuity, the multimeter should be set to the diode test setting which is indicated by the diode symbol. The black probe should be at the cathode end of the diode and the red one be at the anode end before you take the measurement.

Measuring resistance

A proper working multimeter should be able to measure resistance perfectly. With the black probe in the COM port and the red one in the one marked V, switch the dial to the ohm symbol. For an auto-ranging multimeter, the range will be detected for you automatically and al you'll have to do is take the reading.

If you are using the manual ranging one, you'll have to approximate the range, most preferably, you should start with the highest moving downwards. The probe connections to the circuit or component does not matter
