Adjustment value 1:
At the shoulder part of waveform D1, T1 becomes H and T2 be-
comes L, and at the same time, the Y width must not be smaller
than 1/4 of the Z width.
In order to satisfy this value more easily, adjust so that X=Y ap-
proximately and observe the deviation of the waveform.
Adjustment value 2:
At the shoulder part of waveform D1, T1 becomes L and T2 be-
comes H, and at the same time, the Y width must not be smaller
than 1/4 of the Z width.
