How to Use a Clamp Meter

Clamp Meter

You might already have a multimeter and wonder how to use a clamp metre. In this article, you’ll find the answer. A clamp meter is an electrical device with a pair of jaws that open wide to clamp around an electrical conductor. You can read more about these devices by reading the sections below. If you are new to multimeters, however, you may be wondering what they are and why you might need one.


Until recently, a multimeter and a clamp metre were two separate devices. These days, the lines between the two have blurred. A modern device will offer the capacity of both, but is less accurate. If you are an electrician, you should have both a clamp meter and a multimeter. You can check out some of the differences between these two types of meter below. They are used for the same tasks, but can have distinct advantages and disadvantages.

Among the main differences between the two is the range of measurement. The clamp meter is suitable for measuring current up to 400A in small areas. The range of measurement is also small, which makes it suitable for troubleshooting household electronics. However, it is not appropriate for industrial or professional usage. To avoid danger, it is better to buy a multimeter. This meter is fused, which makes it suitable for most household applications.

The multimeter is the obvious choice if you need to measure current, but a clamp metre is a safer option for those not familiar with electrical currents. A clamp meter is a handheld device with sensors built into its body, which allows you to clamp the device to a wire. The result will be an accurate measurement. This tool is ideal for basic tests, such as checking circuit continuity, where accuracy is not an issue.

While multimeters can measure multiple parameters at once, a clamp metre will be more useful for low-level measurements. The meter’s jaws can be closed around a conductor to measure the current. It can also measure resistance, which will be useful if you’re looking for a small current. Using a multimeter will give you higher accuracy and resolution than a clamp metre. They are a must-have for any electrician or electrical professional.

A clamp metre is similar to a multimeter, but has an end-clamp. Clamp meters are highly portable and easy to use, requiring only one hand to operate. Unlike a multimeter, a clamp metre measures the current through electromagnetism, instead of touching the conductor directly. Furthermore, clamp meters can be placed on the outside of an insulated wire, which reduces the risk of electrocution.

While most multimeters can measure a current of up to ten amps, you should consider a clamp metre’s high safety features. While the accuracy of multimeter clamp meters is not as good, they are an excellent option for quick tests and simple testing. However, for professional purposes, you may need a more accurate instrument. A multimeter clamp metre is a good choice for home use or for testing small electrical circuits.

A clamp metre is a good choice if you don’t need to break the circuit, while a multimeter needs to be broken to measure a current. They are also cheaper than a multimeter, so you can buy one without worrying about the safety of your home. A multimeter can also measure voltage and resistance, but they are not as safe as a clamp metre. You will be more comfortable using a clamp meter with a clamp meter because you don’t have to break the circuit first.

Apart from measuring the current, a clamp metre also allows you to check for shorts. To test this, you just turn the wheel to the resistance function and press a button on the face of the multimeter. The result will be a tone that will let you know whether the signal path has been established. Moreover, you can test a wide variety of cables, including the negative lead. In this way, you can easily find out whether you are making use of a circuit or not.

The main advantage of a clamp metre is that it can measure up to 30 feet away, unlike a multimeter. This makes it the ideal tool for testing voltage, resistance, and frequency. Its safety features make it a better choice for electrical engineers and contractors. Besides, the clamp meter can be safer than a multimeter, which may lead to electrocution. However, a multimeter is usually safer and offers greater precision.

The use of a multimeter is more complicated than that of a clamp metre. The former is used to measure voltage and current, while the latter is mostly used to measure current. In addition to measuring voltage and current, clamp meters also measure resistance and inductance. Generally, multimeters are handheld devices designed for measuring AC and DC electrical current. In some cases, they measure both voltage and current. A multimeter clamp meter is also used to log the occurrence of intermittent breaker trips.

A flexible multimeter clamp metre is another option. This device uses a Roowski coil to measure the current. It is a very good option if you need to perform measurements in a small space. The accuracy of the measurement is around 5% and 3%. As such, it is the best choice for HVAC technicians who need to get quick readings on AC voltage, electrical resistance, and volt. The accuracy of the readings can be as precise as possible, thus making it a useful tool.

A Multimeter clamp metre should have a detachable display. These meters allow you to separate the display from the body of the clamp to read the data. Moreover, they can be used remotely by detaching the display. Some advanced clamp meters can measure the motor’s inrush current or the output of a variable frequency drive. This makes it easy for you to perform your measurements. But you should also note that you need to ground the clamp meter for this function.
