Clamp Meters: What to Look for


You need a clamp meter that gives accurate measurements. This means the meter will give the same measurement for a certain amount of current. To ensure accuracy, choose a model from a well-known brand.


A clamp meter is a handheld device that you can use to measure electricity. It should be lightweight, sturdy, and simple to operate. We suggest choosing a device with a bright LCD screen and easy-to-use controls. The meter should also be durable enough to withstand a few bumps and bruises. Ensure that the device works well in dim and bright conditions since you might need to use it in different places.


Some clamp meters offer different data tools, like auto-ranging, holds, and sleep functions. Auto-ranging lets the meter automatically choose the right range for its measuring resistance. This can be helpful if you don’t know what range the current falls into. Clamp meters have an auto-ranging setting that eliminates the need to cycle through numerous settings.

Having a data hold function is helpful. This lets you save and compare measurements. Having a meter that can store more than one measurement is very helpful. Of course, it’s also good if the meter has an auto-shutoff and sleep function so you can conserve battery power without having to try hard to do so.

Measurement Parameters

AC currents can be measured by most clamp meters. On the other hand, some meters can provide information on AC/DC voltage and continuity. Continuity readings must be performed to know if a current is complete and connected.

Resistance measures how well an electric current flows through a device. The higher the resistance, the more difficult it is for the current to flow. Meanwhile, a diode is a device that helps currents flow in one direction. Detailed readings give you a better understanding of electric currents, making it safer and more accurate to fix things.

Frequently Asked Questions about Best Clamp Meter

How accurate are clamp meter?

These meters are usually pretty accurate when measuring AC and DC. They are usually accurate within 2%. Some models are even more accurate, measuring within 0.5%.

What makes a good clamp meter?

Clamp meters that are high quality usually have a long battery life, a high safety rating, and the ability to quickly measure voltage and current. However, low-quality clamp meters also constantly malfunction, run out of power quickly, or give you inaccurate readings. So it’s essential to do your research before buying one!

Do I need a True RMS meter?

If you need to measure the voltage or current of AC signals that are not pure sine waves, then you need a meter that can measure “true RMS.” This is important when measuring the output of adjustable speed motor controls or adjustable heating controls.

Are DC amp clamps accurate?

This meter is accurate to within 5% of the current measurement and 3% of the voltage. It is not suitable for configuration, but it can be used for troubleshooting.

Can you measure DC current with an AC clamp meter?

Hall Effect clamp meters can measure both ac and dc current up to 1000 Hz. They use rigid iron jaws to concentrate the magnetic field around the conductor being measured.

Is multimeter or clamp meter better?

A clamp meter is better for measuring current, while a multimeter is better for measuring voltage, resistance, and frequency.

What is a True RMS clamp meter?

A true-RMS meter can accurately measure waves that are not perfect and are not always the same. This is called root-mean-square. This calculation is used to find out the equivalent DC value of an AC waveform.

Are Southwire clamp meters any good?

The inrush function is a great way to find power problems. The Southwire Smart Clamp Meter is a good tool. I like it because it works well and it is easy to use. It costs $299.

How accurate are digital clamp meters?

These meters are usually pretty accurate with both AC and DC measurements. Specialty models can be even more accurate, measuring to within 0.5%. The vast majority of clamp meters can measure up to 600A AC.

How Accurate Are Clamp Meters?

The current measurements are within 5%, and the voltage is accurate to within 3% of the measured variable. This meter is good for troubleshooting, but it is unsuitable for configuring things.

Do I Need a True RMS Clamp Meter?

A clamp meter is a good choice for measuring current. At the same time, a multimeter is better for measuring voltage, resistance, and frequency. Multimeters have better resolution and accuracy than clamp meters.

Do I Need a True RMS Clamp Meter?

If you need to measure the voltage or current of AC signals that are not pure sine waves, you need a meter to measure the true RMS value. This is important for measuring the voltage or current output of adjustable speed motor controls or adjustable heating controls.

What Is a True RMS Clamp Meter?

A true-RMS meter can accurately measure waves that are not perfect or sinusoidal. This is done by calculating the equivalent DC value of an AC waveform.

Clamp meters are a safer way to measure current. You don’t have to break the circuit to use them. They are used to finding problems with electrical equipment. There are two types of clamp meters: digital and analog.

Can You Measure DC Current With an AC Clamp Meter?

Hall Effect clamp meters can measure both ac and DC up to the kilohertz (1000 Hz) range. They use rigid iron jaws to concentrate the magnetic field that encircles the conductor being measured.

Are Fluke Meters Worth It?

If you only need readings now and then, a less expensive meter will work. A Fluke meter is the best option if you need frequent and highly accurate readings.

What Is the Difference Between Clamp Ammeter and Ammeter?

A clamp meter is used to measure the current (or amperage). On the other hand, a multimeter typically measures voltage, resistance, continuity, and sometimes low current.

What Is Ammeter Clamp?

A clamp meter is a device that measures how much current is flowing through a conductor. It has a current transformer in its jaws that helps it measure the current more accurately.
