The track is positioned adjacent to a path, the path being followed by the first carriage. A second carriage is movable along the track and carries a target. The second carriage is movable between a first position, in which the target is away from the sensor, and a second position, in which the target is adjacent to the sensor and a reference included in the target is a known distance away from the sensor.
