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

How long does the data hold function last?

The data hold function will last until you press "H" again to exit the data hold mode

Which hole do the red and black test leads insert into?

The red test lead connects to the INPUT jack, and the black test lead connects to the COM jack
