6.2.3.3.3.6. Scale calibration
The scale calibration menu allows you to select which scale you want to create. I.e. Focus,
Iris or Zoom. Initially, all scales will be illuminated in red and the “save” function (MB2)
will be grayed out. The scales will only illuminate green after assigning at least one value
for each scale. It is only possible to save the lens file when each axis (with an assigned
motor) is green.
Note: If you do not have a motor connected and assigned to iris and zoom, you must enter
at least one value for each corresponding scale. Please enter the open iris value for the iris
scale and the focal length of your prime lens in the zoom scale.
6.2.3.3.3.7. Focus scale
In general, you can start creating the focus scale from either direction. In this example
however, the lens is being created from infinity to close focus.
Move the control interface assigned to focus (knob as default) until the datum line on your
lens matches infinity.
Use the thumb wheel to scroll clockwise or counter-clockwise until you see “inf” in the
blue input box. As an alternative, you can also swipe the touch screen up or down.
Once “inf” is highlighted in the blue input box, press “set” (MB2) and the infinity mark will
be set on the grafical scale bar. As an alternative, you can also tap the touch screen to
confirm your selection or press the back button (BB1).
