GYROSCOPE AND ACCELEROMETER CALIBRATION
The internal three-axis gyroscope and three-axis accelerometer need to be calibrated for the Horizon overlay
to function properly. The Gyro/Acc calibration file is stored in the flash memory of the BRAIN, so you DO NOT
need to recalibrate after restoring the camera or upgrading firmware. For more information, go to "Horizon" on
page 71.
To calibrate the Horizon overlay, follow the instructions below:
1. Turn on the BRAIN and place it on a level surface.
2. Wait for the camera core temperature to reach room temperature.
3. Go to Menu > Settings > Maintenance > Calibration > Gyro/Acc and select Low Temperature Calibration.
4. After the calibration finishes, wait for the camera core temperature to reach maximum operating temperature.
5. When the BRAIN reaches maximum operating temperature, select High Temperature Calibration.
LENS CALIBRATION
There are many electronic lenses that are compatible with the DSMC Canon Mount or DSMC Nikon Mount, but
are not electronically supported by the DSMC. The Lens Calibration feature allows you to create custom lens
configuration files for these electronic lenses so that you can use rack focus and autofocus.
A custom configuration file might not make an unsupported lens as precise as a fully supported lens. However,
a custom configuration file provides the aperture range and focal lengths so that you can electronically control
the lens with the camera.
NOTE: The camera may not be able to calibrate some electronic lenses.
NOTE: The camera does not create calibration files for lenses that are already electronically supported. For a full
list of supported lenses, go to "Lens Mounts and Lenses" on page 208.
CREATE LENS CALIBRATION FILES
The calibration process creates a calibration file for the current focal length of the electronic lens. Calibrate the
lens at each available focal length to create a full lens calibration file.
1. Attach a DSMC Canon Mount or DSMC Nikon Mount to the BRAIN.
2. Attach an electronic lens.
3. Manually set the first focal length you want to calibrate.
