Applications

This current clamp meter is designed for current measurement in electrical testing, and combines a digital multimeter with a clamping current sensor. The nature of the clamp means that it can fit around a wire at any point to sense AC current and voltage. This has the advantage of allowing electricians to take a reading from a conductor without touching it, which is both more convenient and safer than other methods.

As it is auto-ranging, the multimeter is faster and more user-friendly than manual multimeters where you have to know and preset the appropriate range before measuring.

This current clamp is used for measuring high levels of current in service and maintenance applications. It can also be used when installing electrical equipment.
