To go to the second step (trunnion axis compensation), press the
Trun
softkey.

Sight the second target that is placed more than
30 degrees above the horizontal plane.
2.
Press
[ENT]
to take angle measurements in the
following order:
–
Face-2 to P2
–
Face-1 to P2
–
Face-1 to P1 (Horizontal)
–
Face-2 to P1 (Horizontal)
–
Face-2 to P2
–
Face-1 to P2
–
Face-1 to P1 (Horizontal)
–
Face-2 to P1 (Horizontal)
–
Face-2 to P2
–
Face-1 to P2
The tolerance in angle reading to each direction
is 10". To maintain the accuracy of the
instrument, you must take shots with extreme
care. If the dHA to the same direction is more
than 10", an error message appears, and you
must remeasure all three sets of points.
After three sets of F1/F2 observations, the
instrument calculates the trunnion axis
parameter and the updated ACH (the average of
each set).
If the HA corr. setting is set to OFF, the ACH parameter is not applied to
horizontal angle readings. If this setting is set to ON, both of the ACH and
trunnion-axis parameters are applied to HA. If you do not complete the
second step, the trunnion-axis parameter remains set to zero, and only the
ACH parameter is applied. For more information, see
.
If ACV, ACH, X, or Y is out of range, OVER appears. Press any key to return
to the first observation screen.
