The Profiler Container message box is displayed (this is true also if the pattern
recognition finds the chosen pattern after Step 11 on page -5).
The calibration results are presented as calculated ratios of:
vertical and horizontal screen units called pixels
to

Introduction
12
The Scan Position Offset Calibration procedure scans for data that it then uses to
calculate the X-, Y-axis offsets from the optics and stylus, for positioning the sample
stage.
During the Stylus Change procedure, the system automatically sets up the Scan
Position Offset Calibration to be performed as part of the procedure.
See the "Scan Position Offset Calibration" , starting on Page 13-9, for the scan
position offset calibration procedure.

The vertical sensing transducers in the system are not absolute devices and, therefore,
require calibration.

CAUTION:
All vertical ranges must be calibrated. Each calibration
must be performed independently.
