SETUP – SYSTEM CALIBRATION – SCREEN (MENU 7.10.2)
NMC Pro supports two calibration methods:
• Manual Calibration
• Automatic Calibration
Manual Calibration
To maintain accurate screen performance, calibrate the system at regular intervals. There
are two different calibration methods, depending on the way the screen movement is
measured:
•
Time (default screen control)
•
Measured (used when a Screen Position sensor is installed)
