MANUAL ANGLE
SETTING
Next step • Either, press ALL to measure and record the distance and horizontal angles. This will calculate and set
the orientation and return to the Pre-Settings screen.
• Or, press REC to record the horizontal direction only. This will set the orientation and return to the
Pre-Settings screen.

Access Select Coordinates in the STN-ORIENTATION screen.
Orientation with coordi-
nates
Next step
Find an existing backsight point in the pointsearch or enter ENZ coordinates for a new point. Press OK to
continue to Sight target point.
Sight target point
Next step
After each measurement the message, Do you want to take additional measurements appears.
Selecting:
• Yes returns to the Sight target point screen to take an additional measurement. A maximum of five
target points can be used.
• No proceeds to the STN. ORIENTATION RESULT screen.
Result calculation If more than one target point is measured then the orientation is computed using the "least squares
method".

Field Description
Pt. Point ID of the backsight point.
Field Description
BS ID Point ID of the selected, or entered backsight point.
IF THEN
the orientation is only measured in face II the horizontal direction is based on face II.
the orientation is measured only in face I or a
mixture of I and II
the horizontal direction is based on face I.
a target point is measured several times in the
same face
the last valid measurement is used for the computa-
tion.
