DELAY ADJUSTMENT OF THE CONTROL SIGNAL (SUS-D)
A

1 Measure the pulse width of the SUS-D signal. 2 Check the pulse width of the SUS-D input signal for the DK module. Adjust the variable control so that the pulse width of the SUS-D input signal for the DK module becomes the "pulse width of the SUS-D signal ± 5 nsec." Note: For details on measuring points of waveform, see the figure below.
