The Set Collection routine allows you to collect and average sets of angles to multiple foresights.

Setup

The opening dialog is the standard setup dialog shown below that allows the user to specify the instrument and backsight information.

• Confirm NEZ: This button allows you to quickly verify the instrument and backsight coordinate values.
• Configure: This button displays the dialog shown below, and allows the user to specify options available for the way the angle sets are to be collected.

For robotic total stations, the Robotic Set option is available.

Number of Sets: This input box allows you to define the number of angle sets that are to be collected to each point.  An angle set is defined as a direct and reverse reading to the backsight and the foresight (i.e. BD-FD/FR-BR).  If multiple foresights are defined, only a single backsight direct and backsight reverse set of readings will be collected for all foresight points.

Num Dist Rdgs: This input box allows the user to specify the number of distance measurements that are to be taken during each sighting.

Obs Order: This drop list allows the user to specify the order the angles are to be completed. The definition for the abbreviations are Backsight Direct (BD), Backsight Reverse (BR), Foresight Direct (FD) and Foresight Reverse (FR). Since the backsight dialog is the first reading in all cases, only the following options are available:

ü Robotic Set: Only available for motorized, auto targeting instruments. This option will turn all reverse sightings without any assistance from the user. The order will be the same as BD-FD/FR-BR.

ü BD-FD/FR-BR

ü BD-BR/FD-FR

ü BD-FD/BR-FR

ü BD-BR/FR-FD

Angle Only in Reverse Face: This toggle is intended for use with non-coaxial instruments. Only direct face readings will be measured and all reverse face readings will be for angles only.

Auto-Turn: This toggle will allow the motorized instrument to automatically advance to the next position if it was previously measured. The software will pause at the next location and wait for the user to initiate the reading.

Review Individual Reading Data: This toggle will pause the software after every reading and display the measured data.

• Backsight: This button is required to initiate the first reading and backsight orientation for the set collection process. The following dialog will be displayed. The user must measure either an angle only or an angle and distance to the backsight in order to proceed with the OK button. It is recommended that the Set Angle or Set Angle and Read buttons be used to record the initial backsight reading.

Define Foresight Points

After the backsight dialog is accepted, the next step in the process is to enter in the point ID’s for all of the foresight points that you intend to sight. The dialog shown below is intended to receive pre-defined point ID’s beginning in the top left input box then work your way down to the bottom of the left column, then start at the top of the right column and work down to the end.

Take Readings

Once the foresight points have been specified, the next dialog will be determined by the set order. If the next reading was to be FD since the BD was already recorded, then the dialog will prompt as shown below. Pay attention to the prompts in these dialogs as they inform you as to which point and which face is expected based on your configured set order. Press the enter button or select the OK button to record the reading.

Reading Review

Unless robotic sets are involved, after each measurement, a Reading Review dialog appears, where the measurement can be accepted or rejected.

The sequence of shots continues.

Completed Set

At the end of the set collection process is the dialog displayed below. This will be presented after all of the reciprocal calculation and store point dialogs have been dismissed.

• Change Station: This button will take the user to the instrument setup dialog and advance the point numbers so that the originally occupied point is the backsight and the last foresight point is now the occupied point.
• Collect More Sets: This button will take the user to the backsight dialog and maintain all of the previous setup information.
• Review Direct-Reverse Report: This button will allow the user to select the occupied point ID from a list of points that were used with set collection. The software will then generate a report of all of the sets measure from the specified occupation point.

In the figure above, select a point number and tap OK to view the report. The report is shown below.
