Stylus trigger force and adjustment

Spring force within the probe causes the stylus to sit in a unique

position, and return to this position following each stylus deflection.

Stylus trigger force is set by Renishaw. The user should only

adjust the trigger force in special circumstances, e.g. excessive

machine vibration or insufficient force to support the stylus weight.

To adjust the trigger force, turn the adjusting screw anticlockwise

to reduce force (more sensitive) or clockwise to increase

force (less sensitive). A stop prevents damage, which

could be caused by over-tightening the adjusting screw.

Z direction

5.30 N / 530 gf (18.69 ozf)

X/Y direction (50 mm stylus)

X/Y trigger forces vary, depending on trigger direction.

There are 3 high force and 3 low force X/Y directions:

Factory setting for low force direction = 0.75 N / 75 gf (2.6 ozf)

Factory setting for high force direction = 1.4 N / 140 gf (4.9 ozf)

Maximum setting for low force direction = 2 N / 200 gf (7.0 ozf)

Maximum setting for high force direction = 3.5 N / 350 gf (12.3 ozf)

Minimum setting for low force direction = 0.5N / 50 gf (1.7 ozf)

Minimum setting for high force direction = 0.9 N / 90 gf (3.2 ozf)
