Menu for setting the lens functions
1) LENS Type
: Sets type of auto iris.
•
DC
: Iris opens in proportion to a DC control voltage. Also set to
DC when not using an automatic iris.
•
VIDEO : Lens iris is controlled by the video signal.
2) IRIS MODE
: Sets lens iris mode. (Effective only for DC Lens Type).
•
AUTO
: Sets auto iris
•
MANUAL : Used for manual iris and microscopes.
Note:
Please be sure to set the Open Limit and Close Limit in the AUTO
iris mode when using the camera for the first time or after
replacing the lens.
3) IRIS SPEED
: Sets auto iris speed. (Effective only for DC Lens Type).
Sets speed in a range of 0 to 15 at which camera controls the lens iris. Press R to increase and L to
decrease the setting. Hold button depressed for continuous change. Simultaneously press R and L for
about 2 seconds to set to 8.
When lens operation is not stable(hunting), use lower value of iris speed.
4) OPEN LIMIT
: Sets open limit. (Effective only for DC Lens Type.)
Sets the edge of open side of the lens controlled by auto iris. It just aligns it to open according to
specification of lens. Observe the iris and adjust in the range from 0 to 8.0V to precisely where the iris is
fully open. Press R to increase and L to decrease the setting. Press the L and R buttons simultaneously
for about 2 seconds to set to 7.5V.
Since picture quality deteriorates as the iris approaches fully open, Open Limit can be set to where this
does not occur.
