Abstract
A measurement probe, for a co-ordinate positioning apparatus such as a machine tool, is described that includes a stylus holder that is deflectably mounted to a probe housing. One or more sensors are provided for sensing deflection of the stylus holder relative to the probe housing. A processor is included for producing a trigger signal when the deflection sensed by the one or more sensors meets a trigger condition, such as a deflection threshold. The probe also includes an accelerometer for measuring acceleration of the measurement probe. The trigger condition applied by the processor is alterable, during use, in response to the acceleration measured by the accelerometer. In this manner, false triggering can be suppressed.
