Adjusting the Black Balance

The black balance must be adjusted when:

zYou use your unit the first time;

zYour unit has not been used for some time;

zThe ambient temperature has changed substantially;

zThe gain switchover value has been changed; or

zS.GAIN (super gain) has been set with the USER MAIN/ USER1/USER2 button.

1 Set the switches as illustrated below.

AUTO W/B BAL switch:

OUTPUT: CAM

Used to perform ABB.

 

2 Tilt the AUTO W/B BAL switch so that it is positioned at [ABB], then release it.

The switch returns to the central position with the black balance automatically adjusted.

3 During adjustment, the viewfinder displays the following message:

ABB ACTIVE

‹Note

During adjustment, the lens iris automatically becomes CLOSE.

4 The adjustment will take effect in a few seconds and the following message will appear:

ABB OK

The adjusted value is automatically stored in the memory.

‹Notes

zEnsure that the lens connector is connected and the lens iris is CLOSE.

zDuring a black balance adjustment, light is automatically cut off.

zDuring a black balance adjustment, the gain switchover circuit is automatically switched.

The viewfinder screen may flicker and/or display noise; this is not a failure.

zIf you find the black shading annoying after performing an auto black balance adjustment,

adjust the black shading. To do so, go to the menu option DETECTION (DIG), move the cursor (>),

then press the JOG dial button. The menu option DETECTION (DIG) can be found in the <BLACK SHADING> screen, which is accessible from the MAINTENANCE page.

Note that pressing the ABB switch for longer than five seconds automatically performs an auto black balance adjustment, followed by an automatic black shading adjustment. (For more information, see the menu option SHD. ABB SW CTL in [SW MODE] (page 175).)

However, when the remote control unit (AJ-RC10G: optional accessory) is connected, automatic black shading cannot be executed even if the ABB switch is held down.

zTo cancel the automatic black balance adjustment in process (the viewfinder displays “ABB ACTIVE”), flip the AUTO W/B BAL switch down to [ABB] again. If automatic adjustment is cancelled, the value in effect before automatic adjustment will be used.

Retaining black balances

Each value in memory is retained even if the camera- recorder is turned off.
