Gram gauge

Stylus force adjustment allows the spring rate in the probe to be optimised for the type of stylus that is being used. Heavier styli, for instance, require a higher spring rate to ensure that the probe does not trigger under inertial forces during normal machine movement.

Setting the optimum trigger force using the gram gauge maximises probe performance. The gram gauge can be used to set trigger force settings over a range from 4 grams to 35 grams.
