8.3 Generating black (offset) reference
Creation of a black-level reference is only necessary during commissioning or if the gain
values are changed considerably.
You have three options to generate a black reference:
1) Create a black (offset) reference internally (see section 8.3.1Fehler! Verweisquelle

Use this function if you want to perform offset correction directly inside the camera.
2) Use a stored black (offset) level reference image (see section 8.3.2)
Use this function if you have a stored black-level reference image on your hard disk.
3) Prepare camera to acquire a black (offset) reference (see section 8.3.3)
Use this function if you do not have a black-level reference image and want to generate a
black reference with an image acquisition software. You can directly perform an offset
correction after grabbing the black reference. The reference wizard guides you through
this process.
