Renishaw LP2 Installation Guide

LP2 probe system: System installation
Stylus spring force adjustment
NOTE: LP2 and LP2DD are adjustable, LP2H and LP2HDD are not adjustable.
Stylus trigger force is determined by the internal spring force set by Renishaw. The user should only adjust
the spring force in special circumstances, for example, when excessive machine vibration causes faulty
readings or there is insufcient force to support the stylus weight.
Low force
improves probe sensitivity. To lower the force, turn the key anti-clockwise as far as required: it
will eventually come to a stop.
To increase the force, turn the key clockwise. Take care, as the internal screw will eventually become
disengaged. In the event of this happening, remove any force on the stylus and turn the key anti-clockwise
to re-engage the thread. If this is unsuccessful, return the probe to your supplier for repair.
CAUTION: Stylus spring force adjustment and use of styli other than a calibration stylus type, may cause
probe repeatability to differ from the calibration certicate results.
