A metrological instrument for measuring surface characteristics such as surface form of a component ( ). The instrument includes a slideway ( ) to cause relative movement between a surface sensing probe ( ) and the component which allows the probe to traverse a surface of the component. A probe carriage ( ) supports the probe to allow the probe to move as a body in a measurement direction relative to the carriage so as to follow a surface being sensed. An optical sensor ( ) provides a signal indicative of the displacement of the probe relative to the probe carriage. A controller ( ) acts in response to a signal from the optical sensor, to move the probe carriage so as to maintain the probe in an operational range. A further sensor ( ) measures measurement of displacement of the probe in the measurement direction as it follows a surface during use of the instrument.
