### Calibrating the FCR25 Probe Changer

The calibration process for Renishaw's FCR25 probe changer represents the steps that would be taken to prepare for using any of the probe changers supported by PC-DMIS. The process discussed here is specific to the FCR25 probe changer.

Two inserts are used with the FCR25 rack to accommodate different probe types, the PA25-SH and the PA25-20.

PA25-SH and PA25-20 Inserts

For example, the following image of an FCR25 probe changer shows three ports, two with inserts and one without (probes are also shown). The left port shows a PA25-SH insert and the port on the right shows a PA25-20 insert. The middle port does not have an insert.

Important: The FCR25 Probe Changer must be mounted on the machine table parallel to either the X or Y axis for successful calibration. The FCR25 Probe Changer can be mounted to your table with the MRS rack or the 3 and 6 port stand-alone racks.
For mounting instructions, consult the documentation that came with your probe changer.
