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.

Do not change Camera mode, Video mode and do not interrupt reference/locking during
the calibration procedure.

the calibration temperature using the
Calibr Temp item. There are two options: 37 C

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

in the viewfinder.
• When the process is finished, the camera can be used normally.

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+ 1080p in 1X speed), (720p+1080i+1080p in 3X speed) and 4K. The
availability of video modes depend on installed licenses.
Full Black
A quicker method to carry out Black Calibration (up to 15 s of running time) is the Full Black
procedure. Full Black can be started both from the CGP and the camera system menu:
In the camera menu, go to the Production Setup > Levels > Black menu. Go to the Full
Black item and select it to start the calibration.
The Full Black calibration procedure starts and takes approximately 10 to 15 seconds to run.
