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. (Figure 29)
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 quali fied Handi
Quilter repair technician.

will show a number that should stabilize at 100 if the sen-
sor is functioning properly. Release the foot pedal to stop

depress the foot pedal a percent of depression will appear
