3. Why to adjust PG delay : To compensate mechanical tolerance by adjustment.
4. Concept of automatic adjustment To adjust 6.5H means to set the time from SW.P to V.Sync at 6.5H. We can do that by compensating the undesired time as long as we can check the time between the two. The micom check the gap between SW.P and V.Sync by resolution of 2 § �(1H à 64 usec ) . After comparing the checked time with actual 6.5H, the difference is compensated and then SW.P is output. With this kind of method, we can get the effect same as manual adjustment in the past. result is saved in an EEPROM so as to keep the data in spite of RESET mode. And also, all the
5. Process In Automatic adjustment mode, The micom makes progress to fix PG delay to 9.14 degree maximum range as controllable as, to get average time from to check SW.P and V.SYNC�s time be read from Tape as 4 times, to compensate the time equivalent to 6.5H. Under the time compensated condition, The micom makes recheck SW.P and V.SYNC�s time, if the result is in the range 6.5H ¡ ¾.0H, then the DATA will be saved to EEPROM, or not repeat this 1 process with adjusted state
