4 . 7 Stage Helix Adjustment
The top of the focus slide has a stage helix adjustment, which allows the
stage to be rotated horizontally. To do this the 2 locking clamps located
beneath the stage must first be loosened. The stage can now be rotated
+/- 15 degrees. The helix indicator (located under the X axis cover shows
the amount of rotation in 5’ increments. Once the desired helix is indicated,
tighten the locking clamps to hold this position.
To restore the helix to the zero (0) position, loosen the locking clamps and
rotate the helix adjustment to zero. Or for a more precise zeroing, use one
of the techniques in the “Machine Installation and Setup” section.
4 . 8 Vertical Stage Adjustment
Vertical adjustment of the work stage is by means of the large hand wheel
on the left below the work stage knee. Or joystick control for motorized
machines.
4 . 9 Mechanical Screen Angular Measurement
The screen vernier and protractor consists of a frosted glass screen
divided into four equal quadrants by precision cross lines and 360 Deg.
protractor markings. The screen is rotated by means of a small hand wheel
on the right of the screen. The mechanical venire protractor can then be
used to determine angles with 1 minute resolution.
4 . 10 Electronic Rotary Protractor (Optional)
The electronic rotary screen protractor is a screen encoder that sends screen
rotation information to the digital readout. The readout displays the current rotary
position of the screen .The readout can display rotary position in either degrees
and minutes or degrees decimal. (1/100 of a degree)
Please refer to the readout manual for instructions on how to change the display
mode or re-calibrate the rotary axis.
