Measurement
Accuracy Index
The accuracy index is a number that indicates the amount of
magnification during stereo measurements. The higher the accuracy
index, the greater the magnification. The greater the magnification, the
more accurately you can place the measurement cursors allowing for
more accurate results.
When taking stereo measurements, you magnify the image, not by
zooming but by moving the optical tip as close as you can to the target.
