Description
When measuring hidden points, the height of the
hidden point measurement device as well as the
target height can be typed in. This option should be
used when the hidden point cannot be directly meas-
ured with a hidden point device but a target point can
be used to calculated the position of the hidden point.
Refer to paragraph "Diagram".
The height of the hidden point measurement device.
This is the distance from the ground to the centre of
the device. Refer to paragraph "Diagram".
The distance from the hidden point to the aimed point.
Refer to paragraph "Diagram".
The offset is automatically added to the measured
distance. Refer to paragraph "Distance offsets at
hidden point measurement devices".
Sets the default method for entering an External
Angle Offset. EAO is an offset angle between the
North of the device being used and WGS 1984
geodetic North. EAO's are applied when measuring
hidden points using a device capable of measuring
azimuths.
No EAO value is applied to the azimuth measurement
received from the hidden point measurement device.
