Recommended styli
High modulus carbon fibre styli are designed to minimise pre-travel and improve accuracy, as the
stem material is extremely stiff. This inherent stiffness makes the following styli most suitable for strain
gauge applications.

The featured range of solid carbon fibre styli ensure the best possible performance of the RMP400.
It is possible that the featured range of solid carbon fibre styli may not be suitable for every RMP400
application and that it may be necessary to select specialised styli configurations to meet specific
application requirements.
In applications where specialised styli are to be used, it may be beneficial to reduce the speed of
probing moves. It has been seen in some cases that specialist styli configurations do not exhibit the
probing characteristics and performance that would have otherwise been expected and achieved
when using standard styli. Reducing the speed of the probing move may, in some cases, improve the
performance of the probe.
When selecting components for an application specific stylus, it is recommended that a configuration
with the least number of components is chosen. The stylus diameter should always be as large as
possible and the overall stylus length kept to a minimum. If a stem with a reduced diameter is required,
then it is recommended that an M4 stem with a short length and reduced diameter is selected.
