# To scan using an SX10 or SX12

Connections to the SX10 or SX12 are not supported when using the TCU5 controller or the TDC600 model 1 handheld.

1. Tap and select Measure / Scanning.
2. Enter the Scan name.

3. To select the area inside the video window that needs to be captured, select the Framing method and then define the frame area.

   Framing method | To define the frame area...
   --- | ---
   Rectangle - corners | Tap in the video window to define the first corner and then tap the diagonally opposite corner of the scan rectangle. If required, tap Complementary frame to select the horizontal complement to the currently defined frame. For example, if you define a frame that is 90°, tap Complementary frame to select the area that is 270°.

   Rectangle - sides

   Tap in the video window to define the left side and then the right side of the scan frame. By default the vertical edges of the rectangle are up to the zenith and down to 148° (164 gon), but you can limit this if required.

   To limit the vertical edges of the frame, tap a third time in the video window. To switch between the upper and lower selection, tap Nadir or Zenith. If required, tap again in the video window to limit the upper or lower edge of the rectangle you have defined.

   If required, tap Complementary frame to select the horizontal complement to the currently defined frame. For example, if you define a frame that is 90°, tap Complementary frame to select the area that is 270°.

   Polygon | Tap in the video window to define each vertex of the polygon scan area.

   Horizontal band

   Tap in the video window to define the vertical edges of the full 360° horizontal band.

   Do one of the following:
   - To define the upper limit of a band down to 148°, tap in the video window above 90° VA.
   - To define the lower limit of a band up to the zenith, tap in the video window below 90° VA.

   To switch between the upper and lower selection, tap Nadir or Zenith.

   If required, tap again in the video window to limit the upper or lower vertical edge of the horizontal band you have defined.

   Full dome | No frame definition is required. The full dome always scans a full 360° horizontally and vertically up to the zenith and down to 148° (164 gon).
   Half dome | No frame definition is required. The half dome always scans 180° horizontally (centered at the HA of the instrument), and vertically up to the zenith and down to 148° (164 gon).

   When the frame is filled it is an acceptable frame; if the frame is hollow then the closing line is crossing another line which must be rectified before you are able to start the scan.

   When defining the frame area, tap Undo to remove the last created frame point, or tap Reset region to clear the framing region and start again.

   The software uses the defined frame area to calculate the Number of points and Estimated time required to complete the scan.

   The time to complete a scan is an estimate only. Actual scan times will vary depending on the surface or object being scanned.

4. Select the required Scan density.

   To check the point spacing for the selected scan density, enter the distance to the target in the At distance field. To measure the distance to the target, tap and select Measure. The value shown in the Point spacing field shows the point spacing at the specified distance.

   Only the Telecamera is coaxial with the telescope. For accurate framing at close range, enter the approximate distance from the instrument to the object being scanned in the At distance field and then define the scan frame. Entering the correct distance ensures the scan frame is drawn in the correct position by correcting for the offset between the Overview or Primary camera and the telescope.

5. To limit the scan range, select the Scan limits check box, and then enter the Minimum distance and Maximum distance values for acceptable scan points. Points outside the specified range will not be stored. To measure the distance to a target or object, tap and select Measure.

6. To capture a panorama image with the scan, select the Panorama check box and specify the panorama settings.

7. To change the tilt tolerance, tap Options and then enter a new value in the Tilt tolerance field. The software automatically checks the tilt of the instrument during scanning.

   If the compensator is disabled, the value entered in the Tilt tolerance field is ignored.

8. Tap Next.

   If you are using the SX10/SX12 Telecamera, or have enabled the Fixed exposure setting, the software prompts you to point the instrument toward the location that defines the camera exposure and/or focal distance that you want used for the image.

   This location is only used for the camera settings. When scanning using a half dome frame, the HA of the instrument when you previously tapped Next is used for the center of the scan frame.

   If you are using the SX10/SX12 Telecamera, make sure the zoom level indicator in the top left of the Video feed shows Telecamera. If the Telecamera cannot focus automatically on the object of interest, tap in the Video toolbar to view the Instrument camera options. Select the Manual focus check box and then tap the arrows to adjust the camera focus.

9. Tap Start.

   The software shows the progress of the scan. When the scan is complete, the instrument returns to its original position.

To cancel a scan that is in progress, tap Esc and then select whether to save or delete the scan. The scanning record and associated RWCX file will still be written if you manually cancel a scan.

To repeatedly scan the same area, you can quickly and easily repeat scans by loading a previous scan in the same job or a linked job. See To repeat SX10 or SX12 scans.
