Criteria for Choosing the Best Multimeters
We’re going to stick our necks out and assume, with absolute certainty, that you put a lot of emphasis on self-preservation when dealing with electricity. As a result, you don’t want to partake in any activities or tasks that increase your risk of electrocution, which would make safety one of the most important concerns when shopping for a multimeter.
All multimeters come with a measurement category rating, often abbreviated as CAT, and it’s the quickest and most fool proof way of gauging the safety level of a particular multimeter. In this regard, you have the CAT I, CAT II, CAT III, and lastly the CAT IV. Level of safety progresses as you move along the spectrum with a CAT I multimeter being an ideal choice for use on circuits not connected to the main power supply. On the other hand, a multimeter with the highest measurement category rating, the CAT IV, allows the user to work directly with a power source.

Additional safety measures the user will need to look out for include but are not limited to internal blast shields, shrouded banana plugs for protecting the probes, wide flanges for preventing slippages, and isolation slots for avoiding arc over, among others. While a multimeter with most if not all these safety features is considerably more expensive, it’s in the interest of self-preservation that we recommend you overlook the affordability factor.
In an ideal world, the readings provided by multimeters would have 100 percent accuracy. Unfortunately, there is a myriad of factors that affect the readings ranging from a possibly shoddy manufacturing process, unavoidable and sometimes inadvertent human error, and use of substandard material during the manufacturing process, to extreme weather conditions. Different from domestic applications, multimeters for commercial use need to be as accurate as possible, and professional electricians would go to all lengths to get the most suitable one for the project. High-end multimeters are renowned for the incredible precision of their accuracy range. However, you need to be careful not to pour your earned money on an expensive multimeter with a high accuracy offering more precise readings if you’re no intention of using it commercially. For domestic applications and projects, anything with a range of between 1.5 and 3 percent accuracy would suffice.
The vast majority of modern multimeters come with several features that aim to increase ease of use and provide for efficiency. Some of the most outstanding features to look out for are ergonomics, the screen or display, and the general construction quality and arrangement of controls or dials on the multimeter. A multimeter with exceptional ergonomics, for instance, provides the user with a firm and secure grip, minimizing the possibility of it slipping off your hands while working. A lightweight and compact tool also fits comfortably in the hands and is easy to manoeuver and control, especially in tight and awkward spaces.
A second convenience feature is the products’ display. The big screen can accommodate more numbers and boast exceptional resolution quality. Also, multimeters with a higher resolution are more adept at detecting the slightest change in the input signal, making them the best options for undertaking the most sensitive electrical projects. Lastly, there is the method of measurement. While some models come with a non-contact voltage detection function, others have contact voltage detection feature, and the third group comes with both. The non-contact voltage detection method is more convenient, time-saving and of course safe. The other convenience features you need to look out for are a built-in flashlight, auto shut-off feature and the hold function for freezing readings for future analysis or comparison.
Design and Construction Quality
One last significant prime consideration for those in search of a usable and functional multimeter is the overall construction quality and design of the product. For the heavy commercial applications, you need a multimeter made of high-quality and durable materials, so it effortlessly stands up to the rigorous circumstances. On a similar note, it should be impervious to shocks and drops and extreme abuse in the busiest work settings. Also, as crazy as this might sound, make a point of purchasing a product finished with a conspicuous colour like yellow or orange. The recommendation is informed by the fact that such colours significantly reduce accidents and are less predisposed to being misplaced on the worksite. It also goes without saying that the multimeter needs to be lightweight and compact for easy and quick manoeuvrability into tight and awkward spots.
How to Use Multimeters
While using a multimeter is reasonably easy and straightforward, there are a few precautionary measures you need to keep in mind before getting started. We’re guessing you don’t want to be electrocuted, so following the guidelines religiously is key. First, you need to ensure no current is flowing through the electrical appliance, system or object you intend to test. There is very little difference between testing continuity, resistance, and voltage.
To begin with testing for continuity, all you will be doing is switching the dial on the tool to the relevant mode, which is continuity test mode in our case, then plugging the probes into their specially designed holes, or ports. The last step involves putting each of the probes on each end of the component or object you want to test. In case the test for continuity is positive, the multimeter should display 1 besides producing a beeping sound to notify you. If on the other hand, the circuit is non-continuous, you will either see a 0 or OL, the abbreviation for open loop, on the display. The two readings are indicative of an electrical problem that needs fixing.
To test for resistance, you have to follow the same procedure. If you left the probes in place, you get to skip this step and just start by switching the machine to the resistance setting. Unless you’re using a digital multimeter, you’ll have to set the range for which you want to test. If in doubt, use the highest setting as you have the freedom of adjusting it afterward. In case the range you set is too high, you won’t get any measurement readings, in which case you have to set or adjust the range repeatedly until you get a measurement reading. As was the case with continuity, a 0 or OL readout means there is no resistance in the circuit or object you’re testing. The procedure remains the same when testing for voltage. Simply put the probes on both ends of the electrical object. Switch the dial to the voltage setting and check the display for a readout. If there is no readout, continue adjusting the range. For digital multimeters, no readout is an indication of an electrical malfunction.
Frequently Asked Questions
Q: Do I really need to invest in a multimeter?
A: While it’s not a must-have, a multimeter is one of the most important tools a homeowner, novice, or enthusiastic Do-It-Yourselfer can have. Commercially, a multimeter is important for very obvious reasons: testing duty cycles, diodes, solenoids, breaker points, electrical switches and several other electrical components with glitches. On a domestic level, multimeters have proved to be indispensable when it comes to diagnosing and repairing simple home appliances such as wall outlets, appliances, control panel boards, cars, toasters and other electrical objects. Consequently, by using a multimeter, you’ll be able to quickly and accurately ascertain whether various circuits are working accordingly and fix them quickly if they are not.
Q: How do I know a multimeter it’s safe to use for diagnosing and repairing different electrical components and systems both commercially and domestically?
A: The surest way of judging the safety of a multimeter is by looking at its CAT rating. There are different multimeters out there, and each one is optimized for different uses. The ore vicinity to the power source, the more hazardous it becomes measuring electrical parameters. If you are solely dealing with electrical components deriving power from a domestic outlet, then a multimeter with a CAT II rating should suffice. If on the other hand, you’ll be dealing with the primary circuit breaker, stick to a multimeter with a CAT III rating or higher. Anything closer to the main power source than the primary circuit breaker will necessitate using a IV CAT multimeter. Reserve CAT I multimeters for testing electrical systems that are not outlet connected.
