Survey - Hidden Points
Step Description
4. SLOPE (F5) to access HIDDEN PT Slope Distance.
5. HIDDEN PT Slope Distance
<Slope Distance:> Type in a distance from the known point to the hidden point.
When a hidden point measurement device is attached to the receiver to measure
the distance, the value is automatically transferred.
6. HIDDEN PT Slope Distance
<Elev Angle:> Type in the elevation angle from the known point to the hidden
point. When a hidden point measurement device is attached to the receiver to
measure the elevation angle, the value is automatically transferred.
<Grade (%):> The grade from the known point to the hidden point is automatically
computed from the slope distance and the elevation angle.
The value for <Grade (%):> can be typed in instead of the value for <Elev
Angle:>. Then <Elev Angle:> is computed automatically.
7. HIDDEN PT Slope Distance
<Horiz Distance:> The horizontal distance from the known point to the hidden
point is automatically computed from the slope distance and the elevation angle.
<ΔHeight:> Available if using heights is configured. The height difference
between the known point and the hidden point is automatically computed from the
slope distance and the elevation angle.
8. CONT (F1) to access HIDDEN PT Hidden Point Measurement.
9. HIDDEN PT Hidden Point Measurement
The horizontal distance is displayed in <Horiz Dist:>.
