How to Use a Clamp Multimeter to Measure Voltage, Current, and Resistance

A clamp multimeter is composed of a current transformer and a multimeter. The core of the current transformer can open when the clamp is squeezed; the wire carrying the current to be measured can pass through the opening of the core without being cut. When the clamp is released, the core closes. A clamp multimeter … Read more

Clamp Multimeter Usage: Measuring Voltage, Current, and Resistance

A clamp multimeter is composed of a current transformer and a multimeter. The core of the current transformer can open when the clamp is squeezed; the wire through which the measured current flows can pass through the gap in the opened core without needing to be cut. When the clamp is released, the core closes. … Read more
