Chapter 2 Measurement
Calibration is necessary for maintaining measurement
accuracy. By performing calibration, the problems caused by
differences among lots are solved and measurement accuracy
is maintained.
Basically, calibration is performed for each exclusive plate
type using exclusive calibrators. However, it will take a long
time to perform calibration for all exclusive plates.
To reduce the time and trouble, this system performs
