• Press the MODE button in the main menu to enter the
first submenu. The limit values for the minimum and
maximum aperture can be defined.
The first display line shows the start value of the aperture,
and the second line the value at the end of the ramp.
• Press the SEL button for longer than 2 seconds. The T-stop
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.
If the compensation range available with the
shutter angle is exceeded, the warning ‘ANGLE
RANGE’ flashes on the display after returning
to the main menu. The settings for the iris or the
shutter angle must be corrected accordingly!
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 shutter angle can be defined.
The shutter angle is automatically adjusted by the
WRC-1 to compensate the exposure, while the iris is
being adjusted. One of the two limit values (minimum
or maximum shutter angle, depending on the adjustment
direction of the iris) 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 first digits
flash in the first or second display line. These 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 first digits are confirmed, and the decimal is
automatically set to ‘0’, by pressing the SET button.
The minimum shutter angle corresponds to the selected
full aperture (smallest T-stop number).
