Probe measurement range

The measurement range of the probe is dependent on the following parameters:
Nominal range of the probe
Mass of the moving structure 50 g (1.94 oz)
Spring rate of the moving structure 135 g/mm (4.76 oz/mm)
Mass of the stylus
Orientation of the probe with respect to gravity
For a vertically orientated probe (e.g. PH10 PLUS at A0°) the effect on the Z­axis measurement range, due to increased stylus mass can
be calculated from:
e.g. for a stylus of 40 g mass:
For a horizontally orientated probe (e.g. PH10 PLUS at A90°) the effect on the Y and Z­axes measurement range, due to the re­orientation
through 90° can be calculated from:
e.g. for a stylus of 40 g mass:

Stylus mass (g)
Spring rate (g/mm)
40 g (1.76 oz)
135 g/mm (4.76 oz/mm)
Mass of moving structure (g) + Stylus mass (g)
Spring rate (g/mm)
50 g (1.76 oz) + 40 g (1.41 oz)
135 g/mm (4.76 oz/mm)
= 0.3 mm (0.012 in)
= 0.7 mm (0.028 in)
