Hitachi HV-D25 operation manual

6) CLOSE Limit: (Lens Type is DC mode.)

Observe the iris and adjust to precisely the largest value (smallest diameter). The setting range is from -128 to Close Limit -1. Press R to increase and L to decrease the setting. Press L and R buttons simultaneously for about 2 seconds to set to -85 for Cosmicar or to -65 for Others.

Notes:

1￿Before this adjustment, set Gain to Normal and Shutter to Off. Return the previous settings after adjusting. 2￿Close Limit needs to be set properly for normal AES coupled operation.

7) IRIS GAIN: Iris control voltage gain adjustment (Lens Type is Video mode).

Adjustment is required when replacing a Video type lens or if using the camera for the first time. The setting range is from -10 to 10. Press R to increase and L to decrease the setting. Simultaneously press the L and R buttons for about 2 seconds to set to 0.

Next adjust the lens Level control to highlight the central marker of the video signal level indicator.

If auto iris does not operate even at the Hi or Low extremes of the Level setting, adjust the Iris Gain setting. 8) REFERENCE: (Lens Type is Video mode.)

Adjustment is required when replacing a Video type lens or if using the camera for the first time. Adjust the lens Level control to highlight the central marker of the video signal level indicator. This is not necessary if the Iris Gain has already been adjusted.

While the auto iris is functioning (neither fully open nor fully closed), press R to flash the Setting characters. Adjustment is complete when the flashing ceases.

Notes:

1￿Before adjusting Iris Gain and Reference, be sure to set the Gain to Normal, High or Max, and Over-ride to 0. Adjustment is incorrect in the AGC mode. After adjusting, return the previous settings.

2￿Reference needs to be set properly for normal AGC coupled operation.
