Calibration Overview
User Calibrations
To obtain the best measurement results, it is recommended that a user
vertical calibration be performed after every 10 hours of continuous use or if
the temperature has changed by greater than 2
calibration.

Dark Calibration
The dark calibration is for electrical measurements if an external O/E is being
used. This calibration measures the optical channel o set signal when there
isn't any light present and then uses this information in performing extinction
ratio measurements. Dark calibrations should be done for the following
