6. Press
[OK]
to automatically rotate the top of the
instrument and telescope through 180
°
.
7. Newly measured tilt correction constant is
displayed.
Compare current "Tilt X" and new "Tilt X".
Compare the constants of "Tilt Y" as well.
If each difference is within the range of ±1’, press
[YES]
to renew the correction angle. <Instrument
constants> is restored.
If the values exceed the above range, press
[NO]
to cancel the adjustment and contact your local
dealer to perform the adjustment.
When entering this screen only for checking
constants, press
[NO]
to return to <Instrument
constants>.
With this option you can check the perpendicularity of the reticle and the horizontal/vertical positions of reticle
lines.
• Check the telescope reticle by sighting the target.
PROCEDURE Check 1: Perpendicularity of the reticle to the horizontal axis
1. Carefully level the instrument.
2. Align a clearly visible target (the edge of a roof for
example) on point A of the reticle line.
3. Use the fine motion screws to align the target to
point B on a vertical line.
If the target moves parallel to the vertical line,
adjustment is unnecessary. If its movement
deviates from the vertical line, have our service
representative adjust it.
