Buying Guide
Our tailored buying guide is designed to assist you in selecting the optimal multimeter, providing essential insights on how to effectively utilize a clamp meter, and ensuring you make an informed decision tailored to your professional needs.
Does Accuracy Really Matter?
Simply put, the accuracy is an essential part of the clamp meter as it determines whether your readings and calculations will be correct or not. Ignoring or not giving much importance to this factor can lead to a serious consequence which can even be fatal. The best clamp meters have an accuracy range of ±5 units. Anything above that is should be totally unacceptable as it can be dangerous and inconvenient.
Which Quantities are Essential for a Good Clamp Meter?
The best clamp meters provide you the basic facility to be able to measure AC voltage, DC voltage, AC current, DC current, resistance and, hFE. Some variants may provide with additional features such as Capacitance, Frequency, type-k temperature, Diode test and continuity which are secondary quantities and are not essentially present in all clamp meters.
What to Keep in Mind about the Jaws?
The clamp jaws are an extremely important part of the clamp meter and should hence be treated with appropriate caution. Make sure the clamp does not have a safety lock inside the jaws as this has a risk of getting stuck and making the jaws completely useless. The jaws should be able to open up to at least 30mm or higher. The greater they can open up, the better chances of comfortably getting the accurate readings.
Is Warranty Important While Purchasing a Clamp Meter?
A clamp meter is an electronic device used in electrical applications to measure several quantities which are essential for different kinds of calculations and measurements. It is therefore important that the clamp meters should have a good warranty. Some of the best clamp meters offer a warranty that usually lasts 2 years.
What are the Ideal Ranges of the Best Clamp Meters?
The best clamp meters have the following ideal ranges
| AC Voltage (RMS) | 0-600V |
| AC Current | 0-400A |
| DC Voltage | 0-600V |
| DC Current | 0-1200A |
| Resistance | 0-60kΩ |
| Frequency | 0-200Hz |
| Capacitance | 0-2500uF |
Final Word
Picking out the right clamp meter is vital to your engineering measurements and instrumentation. After careful evaluation and scrutiny of several different types of clamp meters, we have decided to announce the Fluke 323 True-RMS Clamp Meter as the best clamp meter for electricians. For, not only does it provide the best kind of facilities and completes all safety requirements, it is also a sturdy and stylish device to have in your toolkit.
