1.
Turn the zoom ring fully counterclockwise.
2.
Move the split vision adjustment knob to see the 4 marks.
3.
While turning the head assembly knob clockwise to exert a slight upward pressure, turn the top
Z-adjuster set screw (Use 0.05” hex wrench) in or out until the distances L1 and L2 are equal. (See
DWG # 12A).The vacuum head assembly should be in the top position. The setting of the top
Z-adjuster set screw is now final and should not be altered. If the distances L1 and L2 are equal,
but shifted (See DWG # 12C) the beam splitter must be recalibrated. To recalibrate, follow step
13 in Beam Splitter adjustment.
DWG 12C
4.
Once magnification is set, adjust the height of the Height Adjustment Block, P/N-19993,
(the distance from the nest holder to the gun sight pattern plate.) Refer to DWG # 13. This will
provide a reference when trying to adjust the magnification for placing components in the future.

LAMP POSITION ADJUSTMENT
1.
Remove Gun Sight Calibration Assembly and replace with PCB blank such as OK Ind.
PN: 19703.
2.
Install adjustable V Block (MPVB) and place component such as OK Ind. PN: 19385 (BGA-225)
in the block. Bring down vacuum pick up head until vacuum activates and pick up component
from the adjustable V block. Remove component nest from nest holder.
3.
Using your height adjustment block as a reference place the height adjustment on the nest holder
and carefully attempt to slide under component. Use the Z adjustment knob to adjust the height of
the component so that the component leads just clear the adjusting screw on the block.
4.
Remove the height adjustment block.
5.
Roughly align the matching image on the PCB blank (BGA-225) with the component. Use
the red light adjustment knobs on the side of the arm to adjust light intensity so that both images
can be seen on the video screen.
6.
Turn the split vision adjustment knob counterclockwise to bring the upper left and lower right
corner in towards each other. Split the image approximately 50%. Adjust zoom so that image
fills the screen.
7.
Remove front cover to expose front lamps. Refer to DWG # 14.
8.
Loosen the screw securing the side lamp and front right lamp. Starting with the side lamp,
position the bracket to give the most light on the top left hand corner of the PCB. Position the
right lamp so that it provides equal intensity on the lower right corner of PCB. Tighten screw and
secure in place.
9.
Loosen the screw securing the front left lamp and position so that it provides equal illumination on
component. Tighten screw and secure into place.
10.
Reinstall front cover and ensure that screws are tight.
