The Aim-TTi I-prober 520 is a unique current measurement device. Measurement of current normally requires it to be passed through a closed magnetic loop, typically using a split clamp device. Whereas this is suitable for individual wires, it is of no use for measuring current in PCB tracks. The I-prober 520 uses positional H-field measurement. By placing the insulated tip of the probe onto a PCB track, the current flowing in the track can be observed and measured. The I-prober 520 is supplied with a clip-on toroid assembly which converts it into a closed magnetic circuit probe for measuring current within a wire.
