A multimeter is one of those things that every electrician, hobbyist or professional has simply got to have in their arsenal. A good multimeter is your eyes in any electrical repair situation. It lets you know what’s going on in the circuit, and in doing so, can help you diagnose the problem. Multimeters come in a wide variety when it comes to quality and price – the purpose of this post will be to help you find the best multimeter that money can buy. Our aim is to give you the best bang for your buck and help you find a tool that will serve you for years to come.
Online product descriptions of multimeters can sometimes be obscure if you don’t know what you’re looking for. Should you get a Blue Point or maybe a Fluke? A lot of strange-sounding words that represent parameters you might not be familiar with cause confusion. Because of this, we’ve put together a collection of easy to digest reviews that are brief, concise, and that will hopefully help you make your choice quickly and easily. If you’re interested in buying a multimeter, Amazon promo codes and other deals are just one of the many chances you have to shop & save. Read on!

How to choose the best multimeter?
What is a multimeter?
Now that you have some ideas about which multimeters to check out in your particular price range, let’s briefly discuss what a multimeter actually does, and which characteristics you should look for when purchasing one.
Both the best multimeter and the most basic model are essentially simple devices that are easy to use. To use a multimeter, simply connect the probes to the two ports available on your multimeter. One of the ports is hot; the other is the ground. Connect the other side of the probes to the electrical circuit you want to troubleshoot (the “hot” probe goes to the hot wire, the “ground” probes goes to the ground wire) and then use the knobs to select the parameter you wish to measure.
How do you use a multimeter?
To use a multimeter, simply connect the probes to the two ports available on your multimeter. One of the ports is hot; the other is the ground. Connect the other side of the probes to the electrical circuit you want to troubleshoot (the “hot” probe goes to the hot wire, the “ground” probes goes to the ground wire) and then use the knobs to select the parameter you wish to measure.
For example, if you wanted to check the continuity of a potentiometer, you’d set it to resistance and check if the value of the resistance changes as you turn the potentiometer.
To choose the best model for your, there are a few more things that you should know about them. There are a lot of places you can purchase a good multimeter – AutoZone and Home Depot are the first places where customers go to. But, when buying a multimeter, Walmart sales are yet another great alternative to saving. What also comes into question is the brand of the or one of the Fluke units? But before you take any of this into consideration, you need to have the right kind of info.
Types of multimeters
First off, when it comes to multimeters, there are two types: the analog and the digital multimeter. How to use each of them differs only in the way the values are displayed. Analog multimeters use an old-fashioned dial or arrow to show you the value against a physical scale, while digital multimeters display actual numbers that represent the value of the parameter. Digital multimeters are pretty much the standard today, although you could still get a used analog multimeter that works just fine for potentially less money.
Auto vs manual ranging
The next characteristic to look at would be auto-ranging. If you’ve ever used a classic multimeter before, you’d know that most of the older models use manual ranging – meaning that you have to select the range that the value you’re measuring is going to be in. If you set it incorrectly, you’re going to get very weird numbers or the multimeter won’t work at all. Auto-ranging takes this whole process out of the equation by automatically detecting the range of the value and provides you with an exact measurement every time. Check out the Home Depot multimeter offer for auto-ranging models because they have a great selection.
Then there’s the maximum rating that the multimeter can read and detect. This mostly depends on what you’re going to use the unit for. Voltages, currents, and resistances can vary significantly depending on the purpose, from microvolts to megavolts, and too much voltage or current can damage a multimeter or even cause you harm. This is why it’s very important to look at the maximum rating the unit is designed for and always make sure that you aren’t going to be touching that upper limit.
Finally, of course, there’s price. Blue Point multimeter prices can be quite steep and all of the factors we’ve mentioned above are going to impact the price of the unit. There are actually some more things to consider when deciding whether to go with a cheap or expensive multimeter. Cheaper multimeters will generally have an inferior build quality in terms of isolation (the choice between silicone or PVC on the probes, for example), the durability and feel of the dial and so on.
For example, on the Sears offers some units that go as low as $10, but you should really be careful when the price is this low as it’s a red flag for inferior quality. The multimeter Lowes catalog has some extravagant prices as well. When looking for the best budget multimeter, many people make the mistake of thinking the really cheap unit will cut it, so just be aware that you are paying for the build quality as well. Instead of opting for cheaper models, opt for eBay coupons; that way, you get to buy high-quality, usually pricier multimers, at low price tags! You can get a good unit for just under $100, but do keep in mind that you’ll probably have to re-calibrate it once in a while (which can cost anywhere from $50 to $100).
It’s foolish to attempt virtually any kind of electrical fix, no matter how simple it may be, without having a good multimeter on hand. Without a meter, you’re essentially blind to the problem, and without being able to properly diagnose and troubleshoot, you aren’t going to be able to perform the fix effectively. The best multimeter for your needs doesn’t have to be expensive; as long as you make sure that the build quality is okay and that you’ve got the correct rating, then you have nothing to worry about. After all, even if the price of your desired product is above average, you can always get one of the Groupon coupon codes and deals.
Hopefully, this extensive guide and our multimeter reviews have helped you decide on a multimeter that you’ll be happy with, so you can go back to mending those circuits – or constructing new ones – to your heart’s content. Good luck!
