ARRI WRC-1 - Manual (Page 155)

If the compensation range available with the
iris is exceeded (e.g. the start value is at the
beginning or end of the adjustment range) the
READY LED flashes green and the warning ‘IRIS
RANGE’ flashes on the display after returning
to the main menu. The limit values for the
shutter angle, the iris or the camera speed must
be corrected! The camera can still be started for
test purposes in spite of the flashing warning.
However, the exposure may be incorrect! • Press the MODE button to go to the next submenu.
The limit values for the aperture of the lens are defined,
using the SEL and SET buttons and the handwheel.
One of the two limit values (minimum or maximum
aperture, depending on the adjustment direction of the
camera speed) can be defined; the other limit value is
automatically calculated by the WRC-1.
Press the SEL button for longer than 2 seconds.
Depending on the definable limit value, the T-stop
value flashes in the first or second display line. This
can now be set using the handwheel.
The automatically calculated other limit value is shown
in the other display line.
Press the SEL button again to switch to the next digit.
The selected T-stop value is confirmed, and the deci-
mal is set to ‘0’, by pressing the SET button.
The full aperture (smallest T-stop number) corresponds
to the selected maximum camera speed.
