#### Example of SP25 with Multiple Probes

Suppose your SP25 rack has these six probe assemblies that are always attached to the probe head:

P1 | P2 | P3 | P4 | P5 | P6
SP25M | SP25M | SP25M | SP25M | SP25M | SP25M
SM25-1 | SM25-1 | SM25-2 | SM25-3 | TM25-20 | TM25-20
SH25-1 | SH25-1 | SH25-2 | SH25-3 | TP20 | TP20
2mm by 20mm stylus | 4mm by 30mm stylus | 6mm by 80mm stylus | 8mm by 100mm stylus | 2mm by 20mm stylus | 4mm by 20mm stylus

You would define the slots in the FCR25 rack to hold components making up the various probe configurations. This first table shows the slots that hold components for the above probe configurations.

SLOT 1 | SLOT 2 | SLOT 3 | SLOT4 | SLOT5 | SLOT6
P1 | P1 | P2 | P3 | P4 | P5*
P2 |  |  |  |  |

In detail, the slots would hold these components:

SLOT 1 | SLOT 2 | SLOT 3 | SLOT4 | SLOT5 | SLOT6
SM25-1 | SH25-1 | SH25-1 | SH25-2 | SM35-3 | TM25-20
| 2mm by 20mm stylus | 4mm by 20 mm stylus | 6mm by 80mm stylus | SH25-3 | TP20*
|  |  |  | 8mm by 100 mm stylus | 2mm by 20mm stylus*

Slot 1 contains the SM25-1 module only. It uses no insert for this. This component attaches directly to the SP25 and requires the addition of the SH25-1 with the 2mm stylus found in Slot 2 or the SH25-1 with the 4mm stylus found in slot 3.

Slot 2 contains the SH25-1 stylus holder with an attached 2mm by 20mm stylus. This requires an insert in the slot to adapt the physical characteristics of the slot for this component. This component requires an SM25-1 module (found in slot 1). Once it picks up the SM25-1, the probe assembly is complete.

Slot 3 contains the SH25-1 stylus holder with an attached 4mm by 30mm stylus. This requires an insert in the slot to adapt the physical characteristics of the slot for this component. This component requires an SM25-1 module (found in slot 1) Once it picks up the SM25-1, the probe assembly is complete.

Slot 4 contains the SH25-2 stylus holder and an attached 6mm by 80mm stylus. It uses no insert for this. Once this is picked up, the probe assembly is complete.

Slot 5 contains the SM25-3 with the SH25-3 stylus holder and an attached 8mm by 100mm stylus. It uses no insert for this. Once this is picked up, the probe assembly is complete.

Slot 6 contains the TM25-20 module only. It uses no insert for this. This component attaches directly to the SP25M.

* When used with a single stylus, the TP20 probe module and stylus can be attached to the TM25-20 module while in the slot, and requires no additional rack system. But when used with multiple styli (as in this example), the TM25-20 module has no other components attached while it sits in the slot, but requires the use of additional FCR25 slots with adapters specifically for the purpose of holding the TP20 module/stylus combinations. For this example, the added 3 ports would look like this:

SLOT 7 | SLOT 8 | SLOT 9
P5 | P6 | empty

SLOT 7 | SLOT 8 | SLOT 9
TP20 | TP20 | empty
2mm by 20mm stylus | 4mm by 20mm stylus |

When using P1, the CMM would drop off any existing components. Then it would pick up the SM25-1 found in slot 1 of the FCR25 and proceed to pick up the SH25-1 found in slot 2 of the same rack.

When using P2, the CMM would drop off any existing components. Then it would pick up the SM25-1 found in slot 1 of the FCR25 and proceed to pick up the SH25-1 found in slot 3 of the same rack.

When using P3, the CMM would drop off any existing components. Then it would pick up the SM25-2 and SH25-2 combination found in slot 4. With this, the probe assembly is complete.

When using P4, the CMM would drop off any existing components. Then it would pick up the SM25-3 and SH25-3 combination found in slot 5. With this, the probe assembly is complete.

When using P5, the CMM would drop off any existing components. It would then pick up the TM25-20 body in slot 6 of the FCR25 and proceed to pick up the TP20 module/stylus combination in slot 7 of the FCR25.

When using P6, the CMM would drop off any existing components. It would then pick up the TM25-20 body in slot 6 of the FCR25 and proceed to pick up the TP20 module/stylus combination in slot 8 of the FCR25.

As with other tool changers and probe assemblies, components are dropped off in reverse order from how they are picked up.
