Offset Calibration - AGFA DR 800 User Manual

Offset calibration

The integrated DR detector is set up to automatically perform an offset
calibration every minute. The user can manually trigger the offset calibration
by pushing the Offset Calibration button on the software console.
The DR Detector switch indicates when the offset calibration is ongoing.
Figure 55: Offset calibration ongoing
Offset calibration is not performed automatically while on the NX workstation
a thumbnail is selected for an exposure on the integrated DR detector. If
automatic offset calibration has not been performed for too long, the Offset
Calibration button on the software console will start blinking, to remind the
user to manually trigger the offset calibration by pushing the button.

WARNING:
Image artifacts after delay of offset calibration. Perform the
manual offset calibration as soon as possible when the Offset
Calibration button starts blinking.
WARNING:
Image artifacts after exposure of the system to foreign X-ray
radiation. If another X-ray device (X-ray tubes not connected to
the DR 800 generator) has been used nearby the system and you
are not sure that automatic offset calibration has been
performed (e.g. because a thumbnail on the NX was selected all
the time), perform a manual offset calibration before making
new exposures on the system.
