Pentax R-315(N), R-325(N), R-326 [Leveling], 24

3 PREPARATION FOR SURVEYING

[Leveling]

qRotate instrument horizontally and make two

Leveling screws arbitrarily chosen parallel to

the display.

wTurn 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”.

eTurn two Leveling screws arbitrarily chosen in

an opposite direction mutually and put the vial

of the horizontal Electronic vial in the center.

(Figure A)

rPut the bubble of the lengthwise Electronic

vial in the center by operating the Leveling

screw of one remainder.(Figure B)

tThe 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 ybecause 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°.

yConfirm 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

qto y.
