Page 12: Lp2 Probe Moves
With a double touch sequence, the first move finds the surface quickly, then the probe is reversed to a position clear of the surface before making the second touch at a slower feedrate, thereby recording the surface position at a higher resolution . Start position LP2 probe system: LP2 basics... -
Page 13: System Delays
System delays are repeatable to less than 2 μs and are constant in each direction in which measurement is taken . Delays are automatically compensated for provided a calibration move is made in the same direction and at the same velocity as each measurement move . www.renishaw.com/lp2... -
Page 14: Specification
The maximum force applied will occur after the trigger point (overtravel) . The force value depends on related variables including measuring speed, machine deceleration and latency . These are the factory settings, manual adjustment of the LP2/LP2DD is possible, but not possible on LP2H/LP2HDD . NOTE: For stylus recommendations, refer to the Styli and accessories technical specifications (Renishaw part no . -

Page 28: 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 insufficient force to support the stylus weight. -

Page 33: Calibrating The Probe Length
If a rotary axis on the machine rotates the workpiece into the stylus then different diameter workpieces will touch the stylus at different linear speeds . The measurement speed is therefore likely to be different from the calibration speed and compensation will have to be carried out to account for the different speeds . www.renishaw.com/lp2 3-17... -
