Evaluating the Condition of the System / Component 0
The system / component has no deficiencies. The image quality
test resulted in no differences from required reference values.
The system / component has slight deficiencies that have no affect
on continued operation of the system. However they should be
corrected preventively. The image quality test resulted in no differences from required reference values.
The system / component has serious deficiencies. For safety reasons, continued operation of the system is permitted only after
successfully correcting the deficiencies.
After completing all work steps, an evaluation was performed.

Remarks Regarding the Protocol 1.1
The protocol is valid as proof of quality for one check that must be performed on the system
/ component.
The check must be performed in the specified intervals.
The results of the check are entered in this protocol.
The chapter numbers in front of the checkpoints indicate the corresponding chapters in the
particular instructions (see cover page).
The protocol must be completely filled out by the Customer Service Engineer, i.e.:
• All boxes must be filled out. If a box does not apply to the system or if no entry needs to
be made, check the “n.a.“ box.
• Enter the Serial no.: and the date of the check in the header of each page so that each
page can be allocated to a check date.
• The measurement values for the measurements that must be performed during the
check must also be entered in the open spaces / tables provided for them.
• After completing the check, Page 2 of this protocol must be filled out and signed.
