Multimeter Review GuideMultimeters have come a long way from their first analog days, when they served to help repair and maintain radio and telegraph equipment. Today’s advanced digital multimeters can quickly and accurately gauge all aspects of electronic circuits, including measuring volts, ohms and amperes. We can now also replicate the analog multimeter’s useful ability to record rapidly varying values, as well as offer pinpoint precision across a wide variety of different testing modes.

While all multimeters on the market today precisely measure volts, amperes and ohms, many advanced models also include the ability to measure farads, siemens, decibels, radio frequencies, henries and even the temperature via a thermocouple. These devices are extremely accurate, with many of them able to measure increments as small as 0.1 ohm. Successfully used, a multimeter can quickly and accurately identify problems in circuit flow, engineering design, and critical components of complex electrical systems.

What is a Multimeter?

A multimeter is sometimes known to industry insiders as a VOM, an acronym which stands for Volt Ohm Meter. Generally speaking, a multimeter is a single device that combines the ability to measure several different aspects of electricity, specifically voltage, current and resistance. They are generally used either to repair or troubleshoot electrical equipment, including home appliances, as well as advanced technological equipment like computers.

Some engineers use multimeters as a testing tool when designing new equipment. By having a portable, lightweight, and extremely accurate testing device, the multimeter allows anyone repairing or building an electrical device to quickly determine where, when and how much current is flowing in any particular circuit. Multimeters are also vital components of every mechanics tool set.

Effectively, a multimeter works by using a test probe or probes and measuring an aspect of the current flowing through the multimeter. Sometimes crocodile clips are used, or test leads, or “tweezer” probes for smaller jobs. Once the current that is flowing over the multimeter’s test probe is measured, the results are displayed on the screen. Most handheld multimeters sold today use a battery to generate the test charge, and as such, the battery will have to be changed periodically.

What are the different types?

While some traditionalists still use analog multimeters, most people today rely on the convenience and simplicity of using a digital multimeter. Many of today’s models come equipped with an auto-ranging function, which limits the range of what is being tested so that the multimeter and its display screen do not overload.

Other models include the ability to perform polarity checks on D/C circuit readings to identify the direction of current flow. Other multimeters are so advanced that they effectively function as a low-bandwidth oscilloscope. Some manufacturers offer additional control over the multimeter and include cables and software to connect it to a computer.

Some devices come with available jacks or inputs, including thermocouples, in order to connect exterior measuring devices and sensors, such as a thermometer, to the multimeter. This gives the multimeter additional measuring functionality without having to buy or use an additional tool. Because multimeters are an integral part of working with electrical currents, all of today’s models include some form of advanced fuse to shut off the unit and protect it from a short circuit or overload.

In the United States, digital meters, including multimeters, that measure electricity contain fuses rated in Categories I-IV, with the higher numbers indicating higher resistance.

What are the advantages of owning one?

Depending on your electrical engineering skills, a multimeter can be one of the most important tools to have in your home or vehicle. While advanced designers can use multimeters to test new products or design ideas, even amateur home tinkerers can benefit from having a multimeter on hand. Simple DIY repair projects, such as fixing a simple home appliance like a lamp or a toaster, can be made vastly simplified by the use of a handheld digital multimeter.

Using a test probe to quickly verify the functionality of circuits leads to quick fixes or swapping parts, saving car owners and property managers money and grief. Anything electrical in the house, from computer mice to the mains power itself, as well as electrical components in automobiles and boats, can be measured and analyzed with a multimeter, quickly identifying problem areas or troubled circuits. Sometimes expensive and complicated equipment can cease working due to a single chip or circuit malfunction.

A multimeter allows anyone who can read a screen and hold a pen perform to precision readings on any electrical device or circuit.
