A clamp multimeter is a versatile electrical testing tool made of a durable plastic or rubber casing with a digital display screen, a set of test leads, and a clamp mechanism that can be opened and closed around a conductor to measure current flow. The primary use of a clamp multimeter is to measure alternating current and direct current current levels in electrical circuits without the need to disconnect them.

Advantages of Clamp Multimeter
Safety – Clamp multimeters provide a safe method of measuring current since users no longer need to make direct contact with a live wire, avoiding potential danger.
Non-invasive Current Measurement – One advantage of clamp multimeters is their ability to measure current without the need to disconnect the circuit which is especially useful in situations where shutting down the circuit is considered impractical or unsafe.
Data Logging – There are also clamp multimeters that have a data logging feature which allows users to be able to record and analyze measurements over time.
Disadvantages of Clamp Multimeter
Limited Accuracy – While clamp multimeters are convenient for measuring current, they have lower accuracy compared to traditional multimeters, especially in lower ranges which is a great disadvantage in many applications.
Interference – Clamp multimeters are susceptible to electromagnetic interference from nearby sources, which can greatly affect the accuracy of the measurements.
Limited Range – Clamp multimeters typically have a limited current measurement range when you compare them to traditional multimeters which is why for very high or very low currents, a different type of instrument is required.

FAQs
What is the function of a clamp multimeter?
The clamp multimeter is a type of electrical testing tool that has both the functions of a digital multimeter and a current sensor.
How do you measure current with a clamp multimeter?
To measure current with a clamp multimeter, simply follow these simple steps:
- Open the clamp and place it around a single conductor of the circuit you want to measure.
- Set the clamp meter to the appropriate current range and function.
- Read the current measurement on the display.
How accurate is a clamp multimeter?
The accuracy of a clamp meter depends on various factors, including the model and quality of the meter, which means that higher-end clamp meters offer better accuracy than lower-end clamp meters.
Are clamp meters safe to use?
Clamp meters are generally safe to use, but it is still very important to follow safety precautions when you are working with electrical circuits.
What is the difference between a clamp meter and a multimeter?
While a multimeter can measure current by breaking the circuit and inserting the meter in series, a clamp meter measures current by detecting the magnetic field generated by the current flowing through a conductor.
