# To repeat SX10 or SX12 scans

If you are using a Trimble SX10 or SX12 scanning total station to scan the same area multiple times, you can quickly and easily repeat scans by loading a previous scan in the same job or a linked job. For example, you can scan a floor once to find the high or low areas that need leveling, and after performing remedial work you can repeat the scan to confirm the floor is within the required tolerances.

To load a scan:

- The instrument must be set up on the same point as the scan you want to repeat.
- Make sure the At distance value is accurate so that the software can correctly recalculate the vertical angles and account for differences in instrument height between the scans.

To load a previous scan

1. Tap and select Measure / Scanning.

2. Tap Load.

   The software shows a list of all of the scans in the current job and linked jobs that have been taken at the same point as the current station.

3. Select the scan to load.

   The Scanning screen shows the scan parameters of the selected scan, including the scan frame. The Scan name is automatically based on the name of the loaded scan.

4. If required, edit the scan parameters.
5. Tap Start.

To save scan parameters without scanning

You can define scan parameters and save them to load later, without having to complete the scan.

1. Tap and select Measure / Scanning and define the scan parameters, including the frame. Alternatively, load a previous scan and modify it.

2. Tap or swipe right to left (or left to right) along the row of softkeys and tap Save.

   A scan record containing zero points is written to the job. Note that there is no associated .rwcx file for an empty scan.

If you create an empty scan and then later do not want it to appear in the list of scans to load, you can delete it in the Review job screen.
