5. Press [OK]. The coordinate value of the intersection point is
calculated and displayed.
• When there are 2 intersections, [OTHER] is displayed.
 " 2 Intersections"
• Press [S-O] to move to setting-out measurement of the
required point.
"15. SETTING-OUT MEASUREMENT"
6. Press {ESC}. Continue the measurement (repeat steps
from 2).

• It is also possible to perform intersection measurement by pressing [INTSCT] when allocated to the OBS
mode screen.
 Allocating [INTSCT]: "33.11 Allocating Key Functions"

2 Intersections
2 intersections are defined according to 1
Intersections created from Azmth 1 and H.dist 2 (or H.dist 1 and Azmth 2):
An azimuth angle has already been set for a point. The furthest point from this point is set as Intersection
Pt. 1, and the closest point set as Intersection Pt. 2.
• Intersections created from H.dist 1 and H.dist 2:
Intersection to the right of the straight line between 1
point to the left set as Intersection Pt. 2.

Precaution when performing intersection measurement
In the following cases the coordinates of intersection points cannot be calculated.
When Azimuth 1 = Azimuth 2.
When Azimuth 1 – Azimuth 2 = ±180°.
When H.dist 1 = 0, or H.dist 2 = 0.
When the coordinates for 1
st
Pt. and 2
st nd
Pt. and 2 Pt are the same.
