6.5.4 Taking Stereo Measurements
To take stereo measurements, complete the following steps:
1.
Attach the stereo tip securely, and verify that it has been installed correctly.
2.
Position the probe tip for maximum accuracy. Do this by centering the item of
interest to be measured, while maximizing its magnification.
3.
Freeze the image. Stereo measurements require a sharp focus for the best
results.
4.
Select the measurement type and the optical tip.
5.
Place the cursors in the left image .
Measurement accuracy depends on all cursors being positioned accurately. To
ensure accuracy, press the right soft key to activate the zoom window
for a close-up view of the image around the active cursor. As the first cursor is
moved, the matching cursor in the
right image moves accordingly.
6.
Inspect each matching cursor as soon as it appears.
7.
Do not become complacent in reaction to high match strength values. Always
scrutinize the matching cursor’s location.
8.
If a matching cursor is not placed correctly, use the left soft key to go
back to the frozen image and start over or recapture a better image.
9.
When the measurement result is displayed in the blue background, use the
joystick to position it at a convenient location that is not blocking the item of
interest.
10.
Save the image, or press Freeze/Ente r to allow repositioning of any of
the cursors or to reposition the location of the measurement result.
