1. Place and secure the tribrach onto the tripod, and then secure the
instrument onto the tribrach.
2. Using the tribrach footscrews, level the instrument with the elec-
tronic level. To activate the electronic level, turn on the instrument,
and, if tilt correction is set to On, the Level & Plummet screen
appears automatically. Alternatively, press the
any app and select Level.
3. The bubbles of the instrument and tribrach levels must be centred. If
one or both circular levels are not centred, adjust as follows.
Instrument: If the bubble extends beyond the circle, use the Allen
key supplied to centre it with the adjustment screws.
Tribrach: If the bubble extends beyond the circle, adjust it using the
adjustment pin in conjunction with the adjustment screws. Turn the
adjustment screws:
• To the left: and the bubble approaches the screw.
To the right: and the bubble goes away from the screw.
•
4. Repeat step 3. on the instrument and tribrach until both circular lev-
els are centred and no further adjustments are necessary.
After the adjustment, no adjustment screw should be loose.
