Measurement
The microscope is now calibrated and ready to measure.
Replace the workpiece on the Table, refocus the image using the
coarse and fine focus only. Do not change the magnification.
Use the crosshair cursors to measure any visible feature. Here
the drill bit measures .044 inches in diameter.
Changing the focus with the Vertical Slide and Focus Knob for
different areas of interest or different parts is OK as long as the
magnification remains the same.
Other cursors may be selected by clicking the Settings button on
the toolbar, selecting 'Measurement' at the left and choosing an
alternate cursor style from the list. Calibration should remain
valid after changing cursors.
If the Zoom ring or Working Distance ring is moved, calibration
must be re-done.
