The external adjustment for the number of demagnetization pulses per Release cycle is done using the full, residual, release
pushbuttons, and the Variable potentiometer. To adjust the number of release pulses, the control must be “at the end of the
release cycle”. The procedure for externally adjusting the number of Release pulses is as follows:
1. Hold the Release button down and PRESS the Full button. With some control revisions you may have to press the Full
button again after you have let go of the Release button.
2. Using the table below, you can adjust the number of release pulses by turning the Variable adjustment knob.
