Move the slide slowly and steadily by hand in the specified phasing
direction to generate the Hall waveform.
5. Check for proper logic levels (approximately 0V = low, V+= high) and
correct signal sequence (S1 leads S2, and S2 leads S3) with approximately
120° electrical spacing between signal transitions.

6. Before assuming a Hall module fault check Hall field wiring or drive Hall
circuit interface.
