SP80H specification

Stylus carrying capability

Due to the different orientation of the kinematics problems can occur when trying to support heavy styli on SP80H. Failure to reseat properly after the kinematics have been reseated may be observed with styli that have a moment at the stylus root greater than 200 g at 200 mm.

A graph representing a safe working moment range is shown below; this is based upon stylus weight and centre of gravity (COG) distance from the stylus root. It is advised that where possible customers should try and use styli configurations for SP80H that fall within these guidelines.
