parameter has been exceeded (example: the
selected speed is not available with this camera);
readings with ‘OFF’ in the first display line
indicate that this function is deactivated on the
camera (example: shutter angle of the 435 is
set manually = ‘OFF ANGLE’).
Correct parameters must be set before the
camera is started!
The handwheel is without function in the main menu.
Press the RAMP button when the camera is running to
start the ramp. The camera can be started, by pressing
the RUN button on the WMU-1.
The ramp can be reversed, by pressing the RAMP button
again: the ramp then reverses its direction until it reaches
the start value again. For best results wait until the end of
the ramp.
With most lenses, the T-stops before the end-stops
are not exact due to the tolerances involved. In
order to avoid incorrect exposure, the adjusted
iris range should not contain these values.
With the iris wide open a lens-related reduction
in brightness towards the edge of the image
may occur, looking like an incorrect exposure.
The exact values are dependent on the lens type
and must be determined with test shots.
• Press the MODE button in the main menu to enter the
first submenu. The limit values (minimum and maximum
camera speed) can be defined.
The first display line shows the start value of the
camera speed, and the second line the value at the
end of the ramp.
• Press the SEL button for longer than 2 seconds.
The first digits in the first display line flash.
The required value can now be set using the handwheel.
Press the SEL button again to switch to the next digits.
The first digits are confirmed, and the decimal posi-
tions are set to ‘0’ by pressing the SET button.
The values in the second display line can be set
accordingly.
