Needle Sensor Test
The Needle Sensor test will indicate whether the nee dle
position sensor is functioning properly. Rotating the
hand wheel should result in a "beep" for half of a stitch
cycle followed by no "beep" for the other half.

If you hear a constant beep or no beep at all for a
full 360° rotation of the hand wheel, this indicates a
failed test and the machine should be inspected by a
qualified PFAFF® repair technician.
