Operating Instructions - Rev. 1 / 6.2003

Adjustment of perforation offset is performed via the digipot controls and is also

controllable via the PC keyboard (cursor-, ctrl-, return-key used). The position is

displayed on the VGA monitor.

Adjustment of vertical offset (also called perforation framing) can be done during

initialization in both, display mode as well as in run mode.

In the latter, the system pauses the measurement when the adjust-offset-key is

pressed and goes into adjust mode indicated by displaying the rulers representing

the measurement areas over the perforation hole. After a time-out of two seconds

it continues the measurement.

Self-calibration of the perforation framing is done if adjust-mode is “AUTO”.

Adjust mode ”AUTO” - is useful for unattended longform transfer and defining per-

foration offset.

Changes in film framing are compensated automatically by changing the perfora-

tion framing. During adjustment, Steadiscan correction is interrupted.

If perforation offset is obviously out of range, press “AUTO” button.

Perforation offset will be optimized by the system after op-status (field 1) “running”

is reached.

4 frames

Press again the “AUTO” button to de-select auto mode. This avoids an automatic

re-adjustment of the perforation offset, e.g. during transportation of the film leader.

The H/V-correction-values, sent to the SDC spatial processor, are relative to the

position of a reference frame. They represent the deviation of the current frame

from the reference frame.

The position of the reference frame has to be set by the user

(via Reference SET - or locally by the ’R’ key)
