3 PREPARATION FOR SURVEYING
[Leveling]
q
Rotate instrument horizontally and make two
Leveling screws arbitrarily chosen parallel to
the display.
w
Turn on the Electronic vial function by pushing
the Laser key.
Put the bubble of the Circular vial in the
center of the circle when the display shows
“TILT OVER”.
e
Turn two Leveling screws arbitrarily chosen in
an opposite direction mutually and put the vial
of the horizontal Electronic vial in the center.
(Figure A)
r
Put the bubble of the lengthwise Electronic
vial in the center by operating the Leveling
screw of one remainder. (Figure B)
t
The procedures are different according to the
state of the Automatic inclination correction as
following.
[When using the Automatic inclination correction by 2 axes]
Please read procedure
y
because the horizontal angle and the perpendicular
angle error by a perpendicular axis are automatically corrected.
[When using the Automatic inclination correction by 1 axis]
The instrument is horizontally rotated by 180° after the bubble of the
Electronic vial is adjusted on the center at a Left circle position side and
confirm that the bubble of the vial is at the center at the right circle position.
[When using without Automatic inclination correction]
Confirm the bubble is at the center even if the instrument is rotated by each
90°.
y
Confirm whether the plummet is on the ground mark. When you confirm it is
not on the mark, loosen the center screw and move the instrument over the
ground mark correctly and fix the instrument by a center screw. Repeat from
q
to
y
.
