Abstract
In a measuring tool, following operations are carried out. In a preset operation, a displacement is detected in response to an instruction from an operating section, and the detected displacement is stored in a storage as a measurement reference value (X). In a measurement value computing operation, a measurement value is calculated based on a difference between the present displacement and the measurement reference value (X). A judgment operation belongs to the preset operation. In the judgment operation, a movable member is judged to be stationary relative to a stationary member when a variation of the displacement detected by the detector at an interval of a predetermined time (T) has continuously been within a permissible range for a predetermined time. When the movable member is judged to be stationary with respect to the stationary member in the judgment operation, the displacement is stored in the storage as a measurement reference value (X).
