9.3.3 Zoom Optics Squareness Squarenes s refers to the alignment of the camera relative to the motion of the metrology stage. If the camera is misaligned (out of square), an image will appear to drift diagonally across the video image as the stage position is moved along one axis. Steps to check squareness: 1. Place the MAG checker or other suitable inspection part on the stage and secure properly. 2. Select the crosshair image tool in software and verify that it is at its defined center position. Please refer to the M3 software manual for details. 3. At low mag, select a point-like feature such as a corner or the standard’s X-Y origin. Using the stage, position it to the center of the crosshair. 4. Zoom to high magnification, then refocus and re-center the point as needed. 5. While observing the feature, slowly move the stage X axis ONLY. (Do not move the stage Y axis.) Verify that the point remains aligned on the X axis of the crosshair as the feature is moved to the left and right within the field of view 6. Report any observed discrepancy. If the error is verified, contact your SKE representative for authorized service. 9.4 Calibration Verification for KMR-200-M3 Calibration should be verified periodically depending on user requirements and systems usage, and should be at least monthly. A calibration verification standard artifact is available from SKE authorized distributors or directly from the SKE service department. Calibration should also be verified after the system has been serviced or moved. The following is a brief description of the steps recommended for the verification of your machine.
