3.2.2 WRC mode

The WRC mode offers convenient programming and easy adjusting of the camera speed, the shutter angle and the iris of the lens.

If the iris control is not activated (IRIS sliding switch ‘OFF’), the OPEN button serves as the PHASE button on the camera ➪ photo.

The left rotary switch (WRC) ➪ photo is for selecting the parameter which is to be changed

(master value; for definition, see Glossary):

•camera speed,

•shutter angle or

•iris.

The right rotary switch (COMPENSATION) ➪ photo is for setting how the change in exposure caused by the adjustment is to be compensated for

(slave values; for definition, see Glossary).

Example: the WRC rotary switch is set to fps, the COMPENSATION rotary switch is set to Iris. The camera speed is adjusted with the handwheel, while the WRC-1 automatically keeps the film exposure constant, adjusting the iris of the lens.

Depending on the chosen settings and the compensation method, different ramp times are possible. The minimum ramp time is calculated by the WRC-1.

Note:

The term ‘adjust’ as used in this instruction

 

manual describes each direct adjustment of a

 

parameter using the handwheel.

 

Parallel to this adjustment, the WRC-1 can

 

automatically compensate the resultant difference

 

in exposure.

 

The term ‘ramp’ describes adjustment actions

 

which automatically take place over a predefined

 

period of time, i.e. these actions are not directly

 

controlled using the handwheel. They run con-

 

tinuously for a predefined period of time after

 

pressing the RAMP button. Resultant differences

 

in exposure can also be compensated for.
