Vertical Angle Offset

When you begin the vertical angle offset routine, you will see the following screen.

Two observations are required, one to record the top or bottom of the object, and a second to measure a distance that is directly underneath or above the new point.

On this screen you determine what order you will make these two measurements. All you need to do is press either the Observe Angle or Observe Distance button.

Note: You can increase the size of the text shown in the grid by setting the Text Size option in the Options screen.

Note: The Quick Measure Modes option in the Options screen will affect what happens when you press the Measure button when you are using the offset routines. If Quick Measure Modes is on, a measurement will automatically be taken. If it is off, the measure button doesn't actually trigger your total station to take a measurement; it simply takes you to the map screen where you can press the measure button once you are ready to take the measurement.

For example if point "B" was the bottom of an underpass, you could measure its height. Usually it is easier if you position the prism so it is directly beneath the point you want to shoot. You would then record a distance observation to this location which will also be the horizontal position for the new point. Then without turning your instrument, you could rotate the scope vertically so it is sighted on the bottom of the overpass. You could then record this observation which will be used to compute the elevation for the new point.

Once you've recorded these two measurements, you will be able to store the new position.

Storing the Shot

After you make your measurements, you will be able to store the new point. Press the Store Point button to store the point.

Raw File Record

In the raw file the OF records represent the measurements that were made. The SS record is the record that was used to compute the coordinate point for the angle offset and will be a compilation of your two shots.
