5.
When you have accumulated enough
horizontal angle between the backsight and the
foresight, press
[MSR1] or [MSR2] to take a
measurement to the foresight.
The averaged horizontal angle appears. This
value is fixed until the process is finished or
cancelled.
HRx = HR∑ ÷ N
HA = BSAz + HRx (normalized)
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 40.1
To take F1/F2 data without taking a distance
measurement, press
[4] or select F1/F2 in the
Angle menu.
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".
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 24.
