17.SETTING-OUT ARC
This mode allows the operator to define an arc from various arc parameters, such as From Pt. coordinates, and
set out this arc as well as points (offsets) along it.
An arc can be defined by inputting arc parameters such as arc radius, angle,
coordinates for the From point, Center point, To point etc. An arc can also be defined by observation of the
From point, Center point, To point etc.
PROCEDURE Defining by inputting coordinates
1. In the second page of the OBS mode screen, press
[MENU]
, then select "S-O arc".
2. Enter the instrument station data.
"13.1 Entering Instrument Station Data and Azimuth
3. Select “Define arc” in <Set-out arc>.
• When
[LOAD]
is pressed, registered coordinates can be
recalled and used.
