### Step 5: Running Stage Calibration

After setting up the calibration, run the calibration and verification sequence. See the "Vision Stage Calibration Dialog Box Options" for additional information about the calibration options.

1. Select the Axis of the stage axis being calibrated.

2. Select the Compensation Factor to be used during calibration.

3. Select the Method for how the Factor will be compensated. For example, a linear calibration can be done using a Linear or Segmented Linear method.

4. Select Calibrate for the current processing Mode. During Calibrate mode the data is being collected. Verify will be selected in Step 9.

5. Current Run shows the active calibration run.

6. Click Start Run to begin the stage calibration.

- You may be prompted to align the standard to the stage. This supports proper alignment of linear standards.

- You may be prompted to move to the zero position on the standard and zero out the stage position. Doing so will synchronize the dialog relative position display with the standard values and make the data easier to understand.

7. Move to the zero position on the standard if using a single axis linear standard by doing the following (Note: If doing the XY calibration with the grid standard you will be prompted to move to and identify a certified target on the standard, as well as the upper left and lower right limits of travel.):

1. If not automatically entered from standard definition in the Stage Calibration Setup dialog box, enter the standard value into the Standard column in the Data list box.

2. Position the stage and crosshair to the standard target position (This step is used if Edge Detection is not DCC).

3. Select Record Point. If doing Z axis points based on focus, a Focus dialog box will be displayed for doing the focus processing.

4. Repeat this for subsequent standard targets until all of the targets have been taken or the stage axis has been traversed.

8. Select Finish Run. If you are doing a single axis run, you will be asked if you are done with this run or if you need to reposition the standard and continue. This is sometimes necessary when the standard is smaller than the stage travel.

9. Change the Mode to Verify if this was not done automatically. During Verify the error correction is being applied.

10. Repeat the steps 6 through 8. This will run the data collection sequence with error correction applied. It is suggested that you do 3 verification runs.

11. Repeat the Calibrate and Verify sequence for each axis (Steps 1 through 10).

12. When completely finished, select the OK button to finish. A basic certification summary file, CERT.TXT, of the calibration process will be created in the PC-DMIS install directory (normally C:\Program Files\WAI\PC-DMIS V43).

13. To have the correct values applied, stop and start PC-DMIS.
