Abstract
A clamp meter is provided for measuring consumption of current and power of an electrical appliance. The clamp meter includes a power inlet port and a power outlet port that are in controlled connection with each other. A current detection element is arranged between the power inlet port and the power outlet port. When the power inlet port is connected to a power source and the power outlet port is connected to an electrical appliance to be detected, with the electrical appliance turned on, the current detection element detects and converts the current flowing through the power outlet port into a digital signal, which is displayed on a display device mounted on the clamp meter, whereby, through the data and information displayed on the display device, a user may get aware of the power consumption of the electrical appliance and abnormality of power consumption thereof.
