Digital Clamp Meter
As a measurement principle, clamp meters detect the magnetic field emitted by current flowing in a wire in order to measure the current value. Unlike instruments like multimeters, this design has the advantage of being able to measure current without requiring that the circuit under measurement be cut.
Current measurements are accurate to within 5%, and voltage within 3% of the measured variable. Like most inexpensive meters, this makes it suitable for troubleshooting but not configuration.
