<p>A dial indicator that presents the position of a measuring probe (4) on a display (6) The measured value can be defined relative to a zeroing point and the dial indicator includes a zeroing initiator (3) used to initiate zeroing of the position. The dial indicator comprises furthermore a zeroing unit that, when the zeroing initiator is activated, delays the zeroing event until a time when the dial indicator is no longer disturbed by the activation of the zeroing initiator. The zeroing unit comprises a unit that receives data signals from the dial indicator about the position of the measuring probe, and that allow zeroing at the earliest when the probe has become dormant. The zeroing unit may also include one or both of a timer and a three dimensional motion sensor.</p> |
