## Using Auto-Inspect Mode

Auto-Inspect mode provides automated inspection of a sequence of points using a Leica tracker. This process is essentially the same as the typical point inspection process except for the fact that the process may run unattended as the tracker moves from one position to the next one automatically.

This process is often used for deformation measurements or repeated stability studies over a long time range. Each of the positions which are going to be auto inspected, are typically equipped with a separate reflector.

For example, some typical cases for Auto-Inspect might include:

- Inspecting four points distributed over the full working range of the laser tracker. Those four points could be inspected automatically at the beginning and end of a part program to verify that the tracker position has not moved during the measurement process.

- Checking the repeatability of ten reflector positions mounted to a large structure. For example, you could measure these ten points every 15 minutes over a time span of 24 hours.

To use Auto-Inspect mode:

1. Open or Create a Part Program.

2. Insert Manual/DCC mode command, and set it to DCC.

3. Insert an On Error command by selecting the Insert | Flow Control Command | On Error menu item.

On Error dialog box

4. Select the 'Missed Probe Hit' Error Type and the Skip Command option selected.

5. Insert Points for each mounted reflector. To insert each point into your part program:

   1. Aim the tracker at the reflector.

   2. Press CTRL+H to take a hit.

   3. Press the end key.

6. Execute program.

In execution mode, PC-DMIS will automatically measure each of these points as follows:

1. The Leica tracker will point to the first point (position).

2. The laser locks onto the positions if possible. If no reflector is there, or no reflector has been found with the current search settings, PC-DMIS will continue to the next feature.

3. Measurement of the point it taken.

4. The process is repeated (step 1 through 3) until all points have been measured or skipped.

For any points that were skipped, an error message "Reflector not Found" will be displayed to alert the operator to the problem(s). Corrective action can then be taken for skipped points. The error contains a message that there was an error, the feature ID for the error and coordinate location of the feature. The created report will also contain a message for any points that were skipped.
