Patriot Calibration
The Patriot was designed for easy calibration. Upon power-up, loosen the large
angle set knob at the back of the head. Depress the dop holder to its most downward
position. At this point, the pivot block will come in contact with a calibration set
screw. Gently hold the dop arm against the setscrew and depress the
calibration/zero set lever switch, located on the right side of the control box. The
display should reset to zero.
This feature can also be used to “cut to zero”. After completing the procedure
above, move the dop arm to the desired cut angle. Tighten the angle set knob. Press
the calibration/zero set lever switch. The display will reset to zero. As you approach
the desired cut angle, the display will approach zero. You can cut to the zero mark
or stop short to allow for polishing to bring the facet in to the desired angle.
The proper method to set the desired cut angle is to move the dop arm upward as
described in “B” above. Stop short of the desired angle and tighten the angle set
knob. (Fig 1). Turn the angle set fine adjust knob (Fig. 1) clockwise until the
display just clicks up to the desired angle. Note the position of the needle on the
dial indicator. Rotate the outer bezel on the dial indicator so that the needle in now
on the last number of the digital display. Continue turning the small black fine
adjustment knob until you reach the desired 100's digit.
Most cutting patterns only specify 1/10 degree settings. This
paragraph is only applicable if 1/100 degree angles are
required.
