(4) Y ramp voltage waveform adjustment.
Turn the VR51 on Y SUS B/D so that waveform A of
(Fig. 2) be 10
5 .
(5) Y set-up voltage waveform adjustment.
Turn VR22 on Y SUS B/D so that waveform B of Figure(2) be
20
5 .
(6) Y set-down voltage waveform adjustment.
Turn the variable resistor VR2(Set _dn_Vy)on Y SUS
B/D so that waveform C of (Fig. 2) be 10
5 .
3. How to adjust ZSUS (Adjustment should be done
after setting Vs/Va to the set voltage)
(1) Vzb(Z bias) voltage adjustment.
For Vzb voltage, measure and adjust the voltage by
applying each of (-) terminal and (+) terminal in DMM to
the both terminals in R111.
Turn the variable resistance of VR3 on Z SUS B/D to set
to 100 ±0.5V.
