OPTIONAL SOFTWARE
The final screen of the learning has been modified to include a suggested
adjustment. ADJ BY: When press SHIFT+SELECT to do the learning, the
ADJ BY and the ERROR value will show ???? for a few seconds. The ADJ
BY value should go to 0000. The partial frame offset (labelled ERROR)
shown should correspond to one of three values as shown in the chart
below.
TARGET PARTIAL
FRAME OFFSET
000 :07
000: 20
000: 34
It is normal for the target value to vary by up to +/- 2 counts.
The value shown depends on which perf type your zero frame was, and
whether the reference frame's footage number is divisible by 3 or not. It is
not important to understand the complex calculations that are being done
by the learning routine.
It is however very important to have only the target ERROR values as shown
