TEST PROGRAM

Press this

key to quit

TEST-OE.

• TEST - OE can be used to test the accuracy of adjustments made on the measuring

optical system (Image rotator and photo sensor)

• Model eye alignment

Place the model eye tool on the centering tool and align it.

Focusing : Adjust the focus by pushing or pulling the J35058 model eye

attaching tool which installs the model eye.

Alignment: While observing the alignment mark, make a rough alignment of the

model eye position by turning the centering knob of the cenrering tool

until the asterisk " * " mark is positioned near the center of the

display.

Then make a fine alignment while observing the "XAL: " and

"YAL:" displays to obtain "XAL: +0.00" and "YAL: +0.00"

respectively.

Make sure that "TOT: 093" or a similar value is also displayed. If

this value is not displayed, adjust the VR3 GAIN control.

• Measurement

measurement starts. The asterisk

mark in the alignment mark moves around

and the "XAL: " and "YAL: " values change as the Image rotator rotates.
