What you need to know about multimeters
Multimeters are the most used devices within the electrical and electronics industry. They are used to test, repair, and check electrical installations and electronic circuits. In the following section of the article, we will explain everything you need to know about the best multimeters Australia.
Are voltmeters and multimeters the same thing?
It is common to confuse voltmeters and multimeters to the point of believing that they are the same. In short, the voltmeter is used to measure the voltage differences between two points, while the multimeter is a much more complete tool, capable of measuring not only voltage but other quantities such as impedance or resistance.
What is a multimeter for?
In general, they are used to measure two or more electrical values in an electrical circuit [1], and some of the main functions include:
- Resistance measurement
- Continuity test
- Measurement of alternating and direct current voltages
- Measurements of current in alternating and direct current
- Capacitance measurements
- Frequency measurements
- AC presence detection
Now that we’ve given you a rundown of multimeters and their many functions, it is time to understand what the most important purchasing factors are. In the following section, we explain the most important features to look for in a multimeter.
Which brand multimeter is best?
Accuracy
The accuracy of a multimeter is usually referred to as tolerance and describes how accurately the measurement displayed reflects the true value of what is being measured. [2]
The tolerance is usually expressed as a percentage of a reading plus a percentage of the total value, and standard multimeters usually have a ± 3% tolerance [3]
Technology has improved in leaps and bounds and the accuracy of current digital multimeters ensure less margin for error.
Materials
Materials are also important when choosing a multimeter. These devices are designed to work with electricity. You will often be working with large currents, so ensuring the equipment is well insulated is imperative. Both the housing and the diodes (the tips) must be insulated for a safe working environment.
True RMS measurements
This factor is what differentiates a cheap multimeter from a professional one. Multimeters without True RMS measure AC signals assuming that the waves are perfect. The waves never reach this condition, resulting in inaccurate measurements. To get real data, you will have to make several attempts and calculate the average.
The actual RMS measurements are not just the average of the absolute value of the curve but provide a rather complex calculation.
A multimeter with an average response and no true-RMS (root mean square) will only be able to give accurate readings on both sinusoidal and nonsinusoidal ac waveforms.
So, with all of this in mind let’s find the perfect multimeter for your electrical work.
1. INNOVA 3300 Hands-Free Digital Multimeter – Best overall
Reasons to buy:
If you need the best automotive multimeter but have a tight budget, this hands-free machine is perfect for you.

FAQs
1. Plug the probes into the ports on the front of the device. The black probe goes into the COM and the red probe is connected to other ports and is dependent on what you want to measure, if measuring voltage ensure it is connected to the port with a V next to it.
2. Set the mode to V with a straight line if measuring DC voltage, or V with a wavy line if measuring AC voltage
3. Connect the red probe to the positive side and the black probe to the other side, and then read the results on the screen.
1. Perform a visual inspection of the unit to ensure there’s no exposed wires or cracks in the casing, or any other physical damage.
2. Test the probes and make sure the multimeter is working correctly
3. Ensure you’re wearing the appropriate protective gear
4. Keep your eyes peeled for any visual warnings on the screen
