How Do I Choose the Best Clamp Meter?

For those of you who are scared stiff of electricity, we bring you glad tidings of great joy: You can measure a wide range of electric properties very safely. Unlike with a multimeter where you have to take measurements by peeling the wire or looking for a naked segment, with a clamp meter, you can take your measurements without peeling, cutting, or breaking any circuits. This makes it much safer than testing with the regular meter.

Aside from safety, another great thing about the clamp meter is its multi-functionality. Depending on the model you get, a clamp meter can measure AC/DC current and voltage, measure resistance, check continuity, and measure crest factor, among other things. Rather than having different meters in your tool bag for measuring different properties, you simply grab one clamp meter with the functions you need and you’re good to go.

Now that we know that the clamp meter should certainly be one of the tools on our tool belt, we will in this guide, help you choose the best clamp meter for you (of course with your help). We will show you things to look out for, features to expect, and tips that will ensure you get the right clamp meter and enjoy using it.
Price
Getting a clamp meter can cost you a lot of money, or not so much money. It all depends on the features that the brand and model you go for possess. There are clamp meters that combine over 7 functions, and there are those that combine 3; there are, of course, several variations between.

Generally speaking, from our research we found good clamp meters for between $20 to over $500. This wide range should give you an idea of the world of difference you can expect between clamp meters of varying costs. Despite this disparity, each product we selected will deliver value for its price.

Be advised that there are cheap clamp meters that you may be tempted to get because of their price. Please don’t, as many of them won’t give you even the little value you expect for whatever cheap price you pay for it. Spend a bit more and get products of good value.
Features
When choosing a clamp meter, there are certain features that we need to look out for and consider to be able to determine which will be best for our needs. Understanding these features will make the job of selection much easier. Some of the features we need to look at include:
  • Display
  • Functionality
  • True RMS
  • Safety
  • Voltage and current rating
  • IP rating
  • Extras
Construction and Design
When precise readings are needed, a clamp meter capable of True RMS-reading should be the meter of choice. This is important because only a clamp meter capable of True RMS readings can accurately measure waves with distortions and those without distortions. Using a clamp meter that’s not capable of True RMS-reading to measure waves with distortions can give results that are up to 40% off. Most people are now going for this feature.

What is the voltage and current rating of the clamp meter you’re going for? For your clamp meter to be useful across a wide range of applications, it needs to have a voltage rating of 600V and current rating of 400A.

To ensure your safety while using a clamp meter, ensure the model you go for has a minimum of a CAT III 600V rating. Most of the models on our list have a CAT IV 600V rating. Another thing to look out for is the IP (Ingress Protection) rating. This will tell you if the model you’re going for is suitable for the environment you want to work in. The higher the IP rating, the safer it is in most environments.

Many clamp meters can perform many functions. Be sure to find one that performs the functions you need. Getting one that does much more may just be a waste of money. Some of the functions a clamp meter can perform include measuring: AC/DC current and voltage, resistance, continuity, capacitance, frequency, power factor, temperature, and crest factor. Get what you need and save money.

This is a sensitive instrument that needs to be built ruggedly to withstand the rigors of the workplace. Ensure your choice is built to withstand heavy use. Regardless of its functions, if it’s built flimsily, it will simply get broken in no time. A good example to go for is a rubber overmold or double-molded design that provides double protection.
Performance and Ease of Use
The clamp meter is primarily a meter that gives a reading on a display. It is therefore important that the display be the right kind for you. Ensure you can easily read it, and if you’ll be working a lot in dark places, be sure to get a display with backlight so you can easily get your readings even in the dark.

Some extras that can come with a clamp meter include: detachable and extendable clamp so you can work better in tight spaces, and built-in light at the jaws to help illuminate dark spaces. This will be essential if you’ll be working in dark spaces a lot, test probes for increased functionality, etc. Check the extra features to know which will be beneficial to you.

A clamp meter requires annual calibration to ensure it keeps giving accurate readings. To be sure your meter is well-calibrated, you must know its full functions. If your clamp meter comes equipped with a flexible current probe, be sure to calibrate it with the meter.

Taking all this into consideration will certainly help you get the right meter and use it well.

What is the Best Clamp Meter?

As you have seen so far, there are different types of clamp meters with different features. Choosing which will be best for you will depend on what exactly you want to use the meter for. It will be a waste of money to get a meter with functions that you don’t need. Decide exactly what your need for a clamp meter is and watch out for the products that have those functions as we begin to review our selected products.
