the lens. Use only the Vertical Slide for coarse
focus and the silver Focus Knob for fine focus.

Calibration (cont'd)
8/ Decide whether to calibrate in inches or millimeters. Then
choose the appropriate scale on the Calibration Reticle. Move
the cursors so that their respective vertical lines are aligned
with convenient marks on the scale as widely separated as
possible.
Note that in order to drag an individual cursor, it must be
grabbed at the intersection of its two axes. If grabbed
elsewhere, both cursors will be dragged together.
Shown here is the yellow cursor's vertical line aligned with '0'
on the inch scale and the reds cursor's vertical line aligned with
.250 in.
