First the end-stops of the lens must be calibrated and the engraved T-stops must be assigned in the WRC-1 (as described below) for each lens being used.
As the end-stops of the iris ring on the ARRIMACROS change when the lens is focussed, the ARRIMACROS may not be used with the LCS or the WRC-1 system.
Before assigning the T-stop values and calibrating the end-stops of the iris ring of the lens, check all the motors you want to use to be firmly attached to the support rods of the bridge plate.
5.5.1 Assigning the T-stops
The adjustable T-stops (1, 1.4, 2, 2.8, 4, 5.6, etc.) must be correctly assigned in the WRC-1 to the various positions engraved on the iris ring of the lens. The iris cannot be remotely controlled until the respective positions have been assigned. This assignment is stored in the WRC-1 in a table (tbl).
•If a lens has not yet been selected and the T-stops have not yet been assigned (condition on delivery from the factory, or the active iris table has been deleted from the memory), a flashing warning appears – ‘IRIS TBL’
– when the WRC-1 is switched on with the IRIS sliding switch set to the position ‘ON’. Press the MODE button once to enter the input mode.
•If a lens has already been selected and T-stops have been assigned previously, the menu for programming the T-stops of the iris is always the last submenu before returning to the main menu in the WRC rotary switch position ‘IRIS’.
Press the MODE button three times in the WRC rotary switch position ‘IRIS’ and the COMPENSATION rotary switch at ‘OFF’ until ‘TBL LOAD’ appears on the display.
