menu before and after the adjustment (see section
11.2.8) and save them to the C:\SIDEXIS\XGRAW directory
along with the time and date!
IMPORTANT
Before starting the service routines for system adjustment,
make sure that no unit movements are active (especially di

Coarse and precision adjustment
using the Diaphragm/system
adjustment menu in SIDEXIS XG
IMPORTANT
The Pan - Sensor adjustment submenu contains a coarse
adjustment and a precision adjustment (precision adjust
-
ment is preset). Always try to use precision adjustment first
when adjusting the sensor. In most cases, previous coarse
adjustment is not necessary.
With SIDEXIS Version V02.20 and higher, a message win
-
dow indicates when a coarse adjustment is necessary.
Only if you cannot achieve your goal with precision adjust
-
ment, e.g. if the exposed area is completely outside the im
-
age field, should you perform a coarse and then a precision
adjustment.
If a coarse adjustment proves necessary, deactivate the
PRECISION ADJUSTMENT
check box and follow the adjust
-
ment steps described in the present chapter to perform a
coarse adjustment.
The steps and correction procedure required for coarse ad
-
justment are identical to those for precision adjustment. The
only difference between the two modes is the size of the im
-
age section considered. Furthermore, there are fewer auxil
-
iary lines in the coarse adjustment mode.
Default values in the Diaphragm/system adjustment
menu in SIDEXIS XG
During the adjustment, the default adjustment values are
displayed in the text boxes of the Diaphragm/system adjust
-
ment menu.
First perform the adjustment with these default values. If
you do not attain the desired result via this automatic
adjustment, you should determine the adjustment values
manually by measuring the exposure with the SIDEXIS
measuring ruler and then overwrite the default values in the
menu.
This procedure is described in the following sections.
