4. Calibration mode
In this menu item you can select the calibration mode.
• A - Automatic calibration every 2 minutes
• M - Manual calibration triggered by the user by a long press on the F key.
• S - Silent calibration triggered by the user by a long press on the F key.
During use, the image quality gradually decreases due to the changing background
temperature of the sensor. This is compensated for by calibrating the sensor at regular
intervals. For this purpose, an internal aperture is closed for a short time and the remain-
ing signal is subsequently subtracted from the image signal as background noise.
You will recognise the calibration process by a quiet clicking sound and you will see the
last image signal as a still image during this time. When the unit is switched on, several
calibrations are automatically performed in the first few seconds, regardless of the
calibration mode selected.
• In
M mode , you determine the timing of the calibration with the internal shutter your-
self. Perform a manual calibration if you notice a deterioration in picture quality that
manifests itself in the form of increased picture grain or streaking.
• You trigger the S mode in the same way as the M mode. However, the internal shut-
ter is not used, so this process is completely silent.
Notice:
Cover the front lens during the calibration process. Otherwise you will see a
superimposed "ghost image".
