Double Bearing, height excluded
Point A - The point from which
Bearing A is measured.
Bearing A - Bearing Angle
α
to
Hidden Point in units configured.
Point B - The point from which
Bearing B is measured
Bearing B - Bearing Angle
β
to
Hidden Point in units configured.
Use ABORT (F1) to abort the
procedure. When Pt from is
highlighted, use NEWOC (F5) to
occupy the point you are currently
at before the hidden point is mea-
sured.
When Bearing is highlighted, the
BRNG (F6) key is available. This
function may be used if you do not
know or have no means of calculating
the bearing. Select a point that lies on
the line AH (see diagram). Occupy
the point and press BRNG (F6).
Input a Point Id and the Direction
(Toward or Away from the hidden
point). Then press OCUPY (F1) and
STOP (F1), STORE (F1) according to
the Occupation Settings. The Bear-
ing will be calculated using this point
and the point you are measuring
from.
A - Point from which Bearing A is
measured
B -Point from which Bearing B is
measured
C -Auxiliary Point (optional)
D -Auxiliary Point (optional)
H -Hidden Point
α αα αα
- Measured Bearing from A
