Adjust video camera membrane screen
It displays a coloured version of the diffraction pattern:
- Adjust the camera gain (bar on the right side) until the diffraction pattern image fills the entire viewing field (green light upper right of screen).
In case the "auto start" is enabled the measurement starts automatically when the osmolality has reached a value less than 75 mOsm/kg and the image is OK. - Press <>.
The measurement starts and the curve starts to appear.
