6. To level the instrument precisely, use the elec-
tronic level:
•
Centre the electronic level of the first axis by
turning two footscrews.
•
Centre the electronic level for the second
axis by turning the last footscrew.
•
Accept with OK.
7. Centre the instrument precisely over the ground point by shifting the tribrach on the
tripod plate.
☞
When the electronic level is centred and both axes are within the tolerance limit, the
instrument has been levelled up.
☞
Repeat steps 6. and 7. until the required accuracy is achieved.
☞
If the instrument is used on an unstable base, for example a shaking platform or
ship, deactivate the compensator. Otherwise, the compensator might drift out of its
measuring range and interrupt the measuring process by indicating an error.
Under some circumstances the laser
dot is not visible, for example over
pipes. In this case, using a transpar-
ent plate enables the laser dot to be
seen and then easily aligned to the
center of the pipe.
4.3 Data Storage
An internal memory is included in all instruments. The firmware stores all data in jobs in a data-
base in the internal memory. Data can then be transferred to a computer or other device for post
processing via a cable connected to the USB port.
Refer to "10 Data Management" for further information on data management and data transfer.
4.4 Main Menu
The Main Menu is the starting place for accessing most functionality of the instrument. It is the
first screen displayed after switching on the instrument.
