ARRI WRC-1 - Manual (Page 86)

86
Note: To check the image in the viewfinder, the iris
can be opened completely by pressing the
OPEN button (if controlled by the WRC-1). The
iris remains open until the OPEN button is
released again. This does not alter the pro-
grammed settings. The OPEN button is without
function while the camera is running.
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 end-stops for the handwheel
(minimum and maximum shutter angle) can be defined.
The first display line shows the value for the left end-stop,
the second line shows the value for the right end-stop.
• Press the SEL button for longer than 2 seconds.
The shutter angle value in the first display line flashes.
The required value can now be set using the handwheel.
Press the SEL button again to switch to the next digit.
The first digits are confirmed, and the decimal is set to
‘0’ by pressing the SET button.
The values in the second display line can be set
accordingly.
• Press the MODE button to go to the next submenu.
To define the values for the minimum and maximum
aperture (if controlled by the WRC-1), use the SEL and
SET buttons and the handwheel, as described above.
The first display line shows the value for the left end-stop,
the second line shows the value for the right end-stop.
