CALIBRATION

and it is important to keep it calibrated and in perfect
condition.
The accuracy of your work is your responsibility, so you
should check the instrument regularly, especially before
a major task.

1. Place the instrument on a tripod 20 m from a wall so
that the X1 side of the instrument is facing the wall,
and turn it on to perform an automatic levelling.
2. Turn on the receiver and centre it on the screen. Mark
the elevation on the wall with "A".
3. Loosen the centre screw of the tripod to rotate the in-
strument 180° so that the X2 side of the instrument
faces the wall. Tighten the screw again.
