Procedures
Black Calibration
• recommended: when the ambient temperature changes by more than 20 °C / 36 °F.
+ ✎
Tip
The best results are achieved when camera settings and calibration conditions are similar to
the intended shooting situation, for example, shortly before a shooting.
How to apply
To start the Black Calibration procedure proceed as follows:
• Switch on power and camera and wait for the system to become fully operational. To
ensure the best black performance, wait until the camera has reached its operational
temperature. This may take up to 30 minutes, depending on the ambient temperature.

Note
The user level must be set to Service to access the Service menu.
Do not change Camera mode, Video mode and do not interrupt reference/locking during
the calibration procedure.
• In the camera menu, go to the Service > Calibrations > Black Calibr menu and select
the calibration temperature using the Calibr Temp item. There are two options: 37 C
(default) or Act (actual) temperature.
• Go to the Black Cal item and select it. The camera starts to warm up or cool down,
depending on the ambient temperature and the selected calibration temperature. The
lens is capped automatically and lens iris is closed during the calibration process. The
Actual (current) temperature can be monitored using the Act Temp item.
• When the camera reaches the selected calibration temperature, the Black Calibration
process starts. It takes up to 80 seconds to complete. During the process, you can
monitor Black Calibration using the status item and a progress indication (%) is shown
in the viewfinder.
• When the process is finished, the camera can be used normally.

Note
It is recommended to carry out Black Calibration when the camera is used under extreme
ambient temperature conditions. Make sure to set the Calibr Temp item to Act before
performing the calibration.
The results of the Black Calibration procedure are stored in the camera’s internal memory.
The new values are used after switching the camera off and on.
Black Calibration affects all video modes within one of the following clusters of video
modes: (720p, 1080i and 1080p in single speed), (720p, 1080i and 1080p in 3X speed) and in
4K video modes. The availability of video modes depend on installed licenses.
