What Is a Multimeter?

As already mentioned, a multimeter is an important electronic tool which measures a number of functions of electricity such as raw voltage, resistance, and capacitance. Most commonly, you use it to test if a wire or circuit is live in order to diagnose where the problem is and fix it properly. In other words, it quickly finds fault in a circuit by checking its completeness and the voltage from a power source.

​Multimeters are unquestionably essential in many areas of technical work, and there are different types you can choose from according to your personal preferences and the intended use. Typically, you can decide on the number of features, specialty probes and add-ons that can be purchased. First of all, though, you have to select between two types- analog and digital.

Analog vs. Digital – Which to Choose?

We have already pointed out that there are two different kinds of multimeters: analog and digital ones. The main difference is in the way the two display the measurements- the analog multimeter uses a dial with a pointer, while the digital one uses a digital screen.

Analog Multimeters

The first multimeters used were, of course, analog and they still exist, though in a much lesser extent, mostly thanks to the fact that they are a cheaper option. They are also better when it comes to voltage fluctuation as the gauge changes in real time and the needle moves smoothly to show how the energy changes.

On the downside, they are less precise and harder to read than the digital models. Analog models are liable to parallax errors when you look at the gauge from the wrong angle, and you always have to make sure to look dead-on at the meter as to avoid any misreading.

The greatest drawback of analog models is that they are able to read only voltage and ohms. If you will use the multimeter only from time to time, and for some minor in-home repairs that do not call for high precision, you can save some money and go for an analog type.

Digital Multimeters

In modern days, digital multimeters are more common and the best option you can choose. They surpass by far the analog models in precision but are also usually more expensive too.

Their digital displays are easy to read, and most of them can read down to several hundredths or even thousandths of a unit.

As a definition digital multimeters offer more functions than the analog ones; even the simplest models are able to read ohms of resistance as well as voltage. Better digital models are often able to give you an accurate reading of almost every aspect of the electric energy you are testing in a matter of seconds.

What Makes the Best Multimeter Best?

When you search the market for a multimeter, you need to keep track of different features and characteristics they offer to ensure you will end up buying the very best one. With a view to make an informed decision you will not live to regret later on, pay attention to the following:

1. Safety Features

Multimeters are rated for different voltages, or at various CAT levels. In order to protect yourself from over-voltage, you have to check if the certain model is safe for the range you will be using it. Both the main voltage and transient voltage have to be considered. Sudden impulses of current can damage the multimeter if your meter’s rating is exceeded, so make sure you are acquainted with all the CAT categories as they are designed to keep you safe.

Cat I

Suitable for use on circuits not connected to the main power supply such as 24V circuits.

CAT II

Suitable for electrical devices which are plugged straight into the power main and most 110V to 240V systems. The circuit has to remain under 100A and have the protection that keeps it under 22,000V.

CAT III

Suitable for most of the applications before the main breaker. This category covers the right protection for devices plugged in continuously to the main such as the three-phase motors of the refrigeration systems.

CAT IV

Suitable for the direct power source into a building from the transformer.

The best multimeters have a fuse which cuts-out if the level of amperage is unsafe, and protects both the meter and you. Some models also cut out when exposed to higher amperage for long, which can be a lifesaving feature.

2. Voltage Range and Accuracy

Most multimeters are rated for a particular range of electrical energy so be sure to check if the model you are interested in corresponds to your needs. Some high-end models can cover a wide assortment of uses, from working with a power main to measuring mV. Check for both AC and DC specifications.

3. Size and Durability

If you work in a field and use your multimeter daily, its size will matter. Often measuring is performed in tight spaces and a smaller meter that can fit the working space is a must.

As dropping tools and numerous other mishandlings are common issues when out in the field you will want a rugged meter with much protection for most applications. Opt for the most durable and the smallest multimeter in your price range.

4. Accessories

With the right accessories, you can expand your meter’s uses and better its practical functionality but make sure that any additional equipment you buy is compatible with your multimeter in every way.

  • Leads- There are two most common types- the ones that are simple tapered pieces of metal and require holding, and clamp style leads that allow you to have one or both hands free while measuring.
  • Temperature probes- They allow you to take temperature measurements without an additional device.
  • Amperage clamps- Read the amperage in a line without the need for physical contact, just open the ending claw, pass it over and let it close.

5. Warranty

It is best that you find a multimeter with the longest warranty available. Most multimeters are covered for at least one year, and if you discover some defects in your meter during that time, you will be able to get the issue resolved promptly.

6. Price

Be aware that you are going to deal with dangerous currents, and if your multimeter malfunctions you can end up hurt, or even worse. Make sure that all safety requirements are met before you decide to save money on a less expensive model.

The Innova 3320 is excellent for such an inexpensive unit and an ideal choice for in home use. It is well designed and built, and we especially liked the side grip texturing which minimizes the chance that you will drop and damage the unit. It runs off 2xAA batteries and has an auto-off feature (15 min) which prolongs the battery life.

The Innova 3320 has an auto-range function, which means it recognizes what is tested, and delivers the wanted measurement at a reasonable response time. However, auto ranging takes a bit more time than the manual one. It is only a CAT II rated meter, not suitable for testing the higher potential voltage and energy. It reads voltage up to 600Vac and 600Vdc, AC/DC current and also has two temperature inputs.

During measuring the display updates three times per second displaying all measurement changes. It also has a Min/ Max feature, but it transfers the meter into manual range; if there is a transient min/max value outside of that range, only 'OL' is displayed. A built-in stand and a wrist strap are both convenient for a true hands-free operation.
