Applications 4
The averaged horizontal angle appears. This
value is fixed until the process is finished or
cancelled.
HRx is not updated even if the instrument is
moved.
6. Press
[ENT]
to store the foresight as a CP record.
Check the PT, HT, and CD values. Then press
[ENT]
to record.
Face-1/Face-2 measurement
To take F1/F2 data without taking a distance
measurement, press
[4]
or select
F1/F2
in the Angle
menu.
If you have already taken a distance measurement to
the target, you can initiate F1/F2 averaging by flipping
the telescope to the other face.
HRx = HR
∑
+ N
HA = BSAz + HRx (normalized)
In repeat angle measurement, the HA is replaced by HR
∑
. The number of repeat angles appears at the top of
the screen (for example,
N= 5
).
Horizontal angles can be measured up to 1999°59'59"5.
This function stores both raw and XYZ data as CP records, regardless of the Store DB setting.
Use Face-1/Face-2 (F1/F2) measurements to obtain maximum accuracy for measuring angles. Using F1/F2
measurements effectively cancels out mechanical constant error, except for some special errors such as the
vertical axis error. For more information, see
Face-1/Face-2 Measurements, page 26 .
For the HA to be adjusted from a F1/F2 measurement, the Backsight must
also have been measured in F1/F2 during the station setup.
