Use  Scale  Factor - The  DICOM  response  curve  shape  is  based  on  the  measured  black  level  and 
Intensity. If the black level or Intensity of the display changes, then the shape of the DICOM response 
curve also changes. If a display is not expected to be re-calibrated for a period of several months, this 
feature can be used to increase the longevity of the DICOM calibration using the knowledge that the 
displays brightness will decrease slightly...

Preferences dialog - Calibration Sensor tab
Sensor Type - selects the model of calibration sensor to use, and shows the current\
 model being used.
Auto-Detect - attempts to detect the selected model of calibration sensor. SpectraView will automatically detect 
the calibration sensor when the application is started, however if the sensor was not connected at that time, or 
if it was being used by another application, then it may be...

Calibration  and  Profile  Steps -  selects  the  number  of  measurement  steps  to  take  when  calibrating  and 
profiling the display. A larger number of steps will generally result in a more accurate grayscale calibration, but 
will increase the calibration time. 32 steps is the recommended setting \
for most applications. 
Recalibration  Reminder  Period  -  sets  the  interval  after  the  display  is  calibrated  until  a  calibration  reminder 
message  is  displayed.  The  default  value  is...
