The bubble of the digital circular level and the arrows for
the rotating direction of the footscrews only appear if the
instrument tilt is within the sensors working range. To
roughly level the instrument, centre the bubble of the cir-
cular level on top of the instrument rst. Refer to 4.3
Instrument Setup.

lar is positioned above footscrew C.

taneously in opposite directions until
the level bubble is approximately on
the vertical center axis of the digital
level bubble .
☞
When levelled correctly, check marks are displayed. If the
tilt of the instrument exceeds 0.110 gon/0.099°, the
digital circular level is out of its working range and there-
fore, its frame turns red. Once the level is within the
working range, its frame turns black.
4. Centre the level bubble alongside the perpendicular axis of the
crosshair by turning footscrew C. An arrow shows the direction of
rotation required.
☞
When the bubble is centred
and the check marks are
displayed, the instrument is
perfectly levelled.
