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. This has the advantage of allowing electricians to take a reading from a wire without touching it, which is both more convenient and safer than other methods.
True RMS (Root Mean Square) reading has advantages over average RMS reading in that it compensates for interfering electronic loads or distorted sinewaves to give an accurate reading.
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.
