CEM DT-9380A AC/DC True RMS Clamp Meter

The CEM DT-9380A is a model of clamp meter used for electrical measurements, capable of measuring both alternating current (AC) and direct current (DC). It typically features True RMS (Root Mean Square) sensing technology, which provides accurate readings for both pure sinusoidal and non-sinusoidal waveforms.

This type of meter is commonly used by electricians and technicians for safely measuring current without needing to make physical contact with the conductor. The clamp design allows the meter to be placed around a wire or cable, making it easy to measure the current flowing through it without interrupting the circuit.
