### Understanding the SP25 Rack System

You can extend the logic from the above topics to the SP25 rack system. This rack can hold two different types of probe components. For one type the slot is calibrated empty, and for the other type a slot is calibrated with an insert.

This discussion will abandon the previous references to SP600, TP2, TP20, and TP200 since the SP25 rack system uses these components instead:

q SP25M

q SM25-x

q SH25-x

The SP25M system can adapt to any of three different SM25 modules for varied styli lengths/weights, and a 4th module for use with the TP20. They all use the same SP25M probe body.

1. SM25-1 Module – This module can only accept the SH25-1 stylus holder, and is used for styli lengths between 20mm and 50mm.

2. SM25-2 Module – This module can only accept the SH25-2 stylus holder, and is used for styli lengths between 50mm and 105mm.

3. SM25-3 Module – This module can only accept the SH25-3 stylus holder, and is used for styli lengths between 120mm and 200mm. Any of these SM25-x modules are capable of touch trigger probing as well as scanning.

4. TM25-20 Module – This module can only accept the TP20 stylus holder, and is only used for touch trigger probing.
