#### Example of Multiple Probe References

Suppose you have these three probes configurations:

PROBE_01 | PROBE_02 | PROBE_03
QuickConnect AutoJoint | QuickConnect AutoJoint | QuickConnect AutoJoint
TP2 | TP20 | TP20
3mmx10mm stylus | 2mmx10mm stylus | 4mmx20mm stylus

The ACR1 will switch between the TP2 and the TP20 probes. The MCR20 will switch between the styli associated with the TP20 probe system(s).

A typical slot definition might look like this:

ACR1 | MCR20
Slot 1 | Slot 2 | Slot 1 | Slot 2
Probe_01 | Probe_02 | Probe_02 | Probe_03
| Probe_03 |  |

In operation, suppose the system is using PROBE_01 and it needs to switch to PROBE_02. The system would:

- Pause the measurement program.

- Travel to the clearance location for the ACR1.

- Return the currently loaded probe to slot #1 of the ACR1.

- Move to slot #2 of the ACR1 and pick up the TP20 body for PROBE_02.

- Use the respective Safety/Clearance points and move to the MCR20.

- Move into slot #1 of the MCR20 to attach the stylus adapter with the desired stylus.

- Return to the MCR20’s Clearance point.

- Continue with the measurement program.

Suppose after measuring some features, the system then needs to use PROBE_03. The system would:

- Pause the measurement process.

- Travel to the clearance location for the MCR20.

- Move into slot #1 to drop off PROBE_02’s stylus.

- Travel out, over, and into slot #3 to pick up the stylus required for PROBE_03.

- Travel to the clearance location.

- Continue with the measurement program.

Now, suppose the system needs to switch from PROBE_03 (the TP20 with the 4mmx20mm stylus) back to Probe_01 (the TP2 with the 3mmx10mm stylus). The system would:

- Pause the measurement program.

- Move to the clearance point for the MCR20.

- Go into slot #2 and drop off the stylus assembly.

- Return to the MCR20’s clearance location

- Move to the ACR1’s clearance location.

- Go into slot #2 to drop off the TP20 assembly.

- Move out and return to slot #1 to pick up the TP2 assembly (the TP2 probe already has the stylus attached).

- Move to the clearance point for the ACR1.

- Continue the measurement program.

Note that in this example, you only need one TP20 probe body. You use the MCR20 to switch between two different probe stylus assemblies for varied measurement requirements.
