Press [F3](YES) key. 4)
The instrument rotates and the
telescope turns to inverted position
automatically and the measurement of
the known point B starts. 3)
When the measurement of point B is
completed, the instrument rotates and
starts the measurement of known
point A in inverted position . 3)
When the measurement of known point
A is completed, the instrument rotates
and the telescope turns to the normal
position automatically .
Vertical angle error (dVA,dVB) and
horizontal angle discrepancy (dH) will
be displayed. 5)
