Always clamp the instrument around only one conductor. Clamping the instrument around
two or more of conductors in a bundle prevents the instrument from measuring any current
regardless of whether the measurement target is a single-phase or three-phase circuit.
Make certain that the current flow direction
arrow points toward the load.
