Remote Elevation

This routine will set the elevation coordinate of the station from a point with
known elevation. It is accessible from within the first station setup screen by
tapping the

Remote Elevation button (provided the 2D Survey box is unchecked).

The known elevation is either that of:

• A point stored in the job. You will select this point from the map or from

the list of points.

• A point not stored in the job, but its elevation is known, perhaps through

past results, by calculation, or printed on a data sheet.

Step-by-step procedure:

• Have a target set up on the point.

• Aim the instrument at the point.

• Go to

Station Setup and then tap the Remote Elevation button.

• Enter the elevation according to the suitable method.

• Check the

HI value.

• Select the target and check the

HR value.

• Tap

Take Shot. The results of the shot then appears in the lower part of the

screen.

• Tap

to return to the Station Setup screen and complete the setup

according to the method you chose.

Fixing Station Setup

You may need to apply corrections to all the measured points sharing the same
station setup. This can be done using the

Fix Station Setup function in the Adjust

menu.

Two types of transformation can be done:

Rotation, based on a known azimuth between two points sharing the same

station setup. You need to specify the value of known azimuth and the two
point names. When applying the change, all the concerned points will be
rotated the same way. The original backsight azimuth will be updated as
well to achieve the desired result (which

Adjust > Rotate would not do).

Translation, based on two points that you specify. The first one is an

observed point that you would like to translate to another location, and the
second one is a key-in point created with the coordinates that you would
like to assign to the first point. When applying the change, all the
concerned points will be translated the same way. The original occupy point
will be moved accordingly to achieve the desired results (which

Adjust >

Translate would not do).
