Stereo Mode Measurement Procedure, Part 2
7
– Tap the screen (or hit ) to display the second cursor. Position it as described in items 5 and 6.
Note: Generally, you get the best results by leaving the matching cursors exactly where the system places them. However, under certain circumstances, such as when a repeating
pattern exists, you may need to help the system find the correct match.
8
– The active dimension appears on the display screen (tapping the number turns its box blue and allows it to be repositioned) along with the Stereo Index and Match Strength
associated with this measurement and cursor placement. See the immediately preceding manual sections for a description of these two concepts.
9
– Select to Add another measurement (up to five are allowed on any display). Once more than one measurement are displayed, select Next Measurement to change which
measurement is active (or simply tap on any existing measurement cursor to make it active).
10
– Tap to access alternate rows of soft keys. Double tapping in this location hides or displays the soft keys and status bar.
11
– Select Options, then Change Tip to retain the image captured and measurement(s) performed while correcting for an incorrectly specified tip serial number. This process
allows the correct calibration data to be applied and eliminates the need to collect additional images simply because the user initially identified the wrong tip serial number.
Note: The Stereo Index and Match Strength shown apply only to the active measurement.
Note: To verify your measurement accuracy, move each left-side cursor a few pixels. If the matching cursors move identically, and if the results change only a little, you have
probably achieved accurate results. But if a matching cursor's movement is erratic, or if the results change significantly, your results are unreliable. capture a fresh image, following
the guidelines above. This step is especially useful if you have to use a low Stereo Index (less than 5) or low confidence number (less than 3). For example, you might have to use
a low Stereo Index if you are measuring a large object or if you have limited access and cannot bring the tip close to the target. You might have to accept a lower confidence
number if the surface has few details.
