• Increasing Video Gain also increases video noise. Use Video Gain sparingly, or not at all. Leave
it set to 1 whenever possible.
• The Black Level will be adjusted automatically each time you perform an Ultracal! calibration

• If cameras with remotely controlled shutters are used the shutter control circuits
must be paralleled to each camera.

is currently selected. If it shows
GREEN
then camera sync is present. If it shows
RED
then
there is either no camera connected, or the connected camera is not operating.
