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 electronic 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 FNC/Favourites key from within any program 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 levels are
centred and no further adjustments are necessary.
After the adjustment, no adjustment screw should be loose.
