Why is it necessary to clamp a single conductor with a clamp meter to measure current instead of the entire power cable?

A two-prong cable has live and neutral wires; a three-prong adds ground. Current flows oppositely in live and neutral wires, canceling magnetic fields. Clamping both may show zero. For accuracy, clamp each wire separately

Where is the NCV function implemented on the clamp meter?

The NCV probe of the clamp meter is located at the protruding part of the clamp tip. Simply bring the clamp meter tip close to the object being detected when using the NCV function
