Adjusting The White Balance - Sony Digital betacam DVW-970 Operation Manual

The black balance adjustment ends in a few seconds
with the message "ABB:OK" and the adjustment value
is automatically stored in memory.
Notes
• During the black balance adjustment, the iris is
automatically closed.
• During the black balance adjustment, the gain selection
circuit is automatically activated so you may see
flickering on the viewfinder screen, but this is not a fault.
If automatic black balance adjustment
cannot be made
If the black balance adjustment cannot be completed
normally, an error message will appear for about 3 seconds
on the viewfinder screen (in display mode 2 or 3).
Possible messages are listed below.
