A clamp meter is a specialized electrical tester that combines a digital multimeter with a current sensor. Its most distinctive feature is the integrated transformer jaws at the top, which allow you to measure electrical current flowing through a wire without having to break the circuit or disconnect any wires.Key Functions and FeaturesNon-Contact Measurement: By clamping the jaws around a single live conductor, it detects the magnetic field to provide a precise current reading.Versatility: Beyond current, it functions as a standard multimeter to measure AC/DC voltage, resistance, and continuity using the included test leads.Capabilities:Measures high AC currents up to 1000A.Features a large LCD screen with a backlight for visibility in dim environments.Includes a data hold button to freeze a reading on the display for reading.
