the Optical Black Reference Calibration Offset. Higher offset values may be required when the
camera is operating at very high temperature and frame rates. Set the FPN Correction Mode to

offset until the result is satisfactory.

Press…command to save the calibration to the selected user set.
For each gain setting required perform and save the calibration; coefficients for each gain setting
are saved in the user set (gain settings for which no calibration is done use default coefficients).
Step 9. To load this user set when resetting or powering on the camera, use the Power-up
Configuration dialog. Click Setting… Power-up Configuration feature, in Camera Information
category.
In the Power-up Configuration dialog box select the required user set both Camera Power-up
configuration and Load / Save configuration and click Save.
This ensures that the camera loads the saved parameters the next time the camera is turned on.
