# Best Clamp meter for Electricians Top 10 Reviews and Buying Guide

By shafiq usama

As an electrical engineer, I love explaining how things like circuits and electronics work. I write on my blog to share simple explanations, reviews, and useful tips about the latest technology.

The unit of electricity measurement is current. That's the reason every electrician needs an electrical tester to measure the precise current of any circuit. Now, if you look around, you will see two variants of electrical testers. Firstly, we have a multimeter with a maximum current measuring capacity of 20A. Secondly, we have a Clamp meter with a maximum current measuring capacity of 1000A. So, it is clear that to measure current; a clamp meter is always a better option. If you look around, you will see many best clamp meter for electricians. Here I have listed down 10 top picks.

### How to measure amps with a clamp meter?

There are some standard methods to measure ac/dc amps with a clamp meter. To know this fact, one must learn about how a clamp meter works. If you clamp a current-carrying conductor, then a magnetic flux will be induced in the coil of the clamp meter. This magnetic flux will then be converted into the current with the help of any controller.

There are some limitations regarding Ac and dc measurements

1. If you clamp a single phase with your clamp meter, you will get the most accurate result on each phase.
2. If you pass two phases through the same clamp meter, you will get the same results with lesser precision.
3. When you pass all three phases from a single clamp meter simultaneously, the result will be zero because all three phases cancel each other flux due to a difference of 120 degrees in each phase. In the same way, if you pass a live and neutral wire through a clamp meter, the result will be zero because of the same conditions mentioned above.

### Is a clamp meter better than a multimeter?

It depends upon the nature of your job. For example, if you are a person who is more connected with electrical troubleshooting, then you need the best digital auto-ranging multimeter for electricians. On the other hand, if you want a DMM for electricians, you can visit our top 10 picks of multimeters for electricians

An electrician or technician has to check running loads more than once for industrial equipment and HVAC systems. For such jobs, a clamp meter is more suitable. If we have to take one side, then a digital clamp meter has more weight-age. A clamp meter can measure all electrical properties with a high current rating, so it is always one step ahead.

### Can clamp meters measure DC Current?

To understand this question, firstly you need to know about the current. Current is basically the flow of electrons in any conductor. The thing which differentiates AC and DC is its direction. In AC circuits, we have a sine wave that moves in a back and forth direction periodically. Like in Fig.01. But in DC, the flow of electrons is steady and unidirectional like Fig.02.

Now coming to the main point, a clamp meter measures DC. As we discussed above, the current is the flow of electrons, so yes, all best clamp meters for electricians can measure both AC/DC.
