15.6 Autocalibration
After the Capture Calibration routine is completed, the user measures surface features contained
within each image and enters their dimensions into the software. The software compares its
estimates with the actual (user-entered) dimensions to make final corrections. This portion of the
calibration is carried out using the Offline > Utility > Autocalibration command.
To utilize the Offline > Utility > Autocalibration command, do the following:
1. Select one of the desired captured calibration images in the Capture directory. Select Offline
> Utility > Autocalibration. The control monitor will display the X-Y Piezo Calibration
dialog box:
Verify that the file name prefix assigned to the captured files from the Capture Calibration routine
described in Section 15.5 above is correct.
2. For normal calibration, verify that all parameters are selected in the dialog box, then click on
Calibrate to execute the routine.
The software sequentially presents various calibration images on the display monitor while
prompting the user to draw either a vertical line or a horizontal line. The control monitor
simultaneously displays various dialog boxes—one for each image—requesting you to enter a
distance.
