The invention disclosed herein is a device, method of use and kit for measuring and precisely setting the dimensions in wheeled and tracked devices or vehicles. It is particularly well-suited for rowing boats and simulators thereof, including but not limited to sweep rowing and sculling watercraft. It introduces a novel gauge and process to adjust wheels within tracked environments to minimize friction and enhance equipment performance. Further, the device is capable of precise measurement of both spread and span dimensions in rowing watercraft to optimize rigging.

A screw thread measurement system and methods may comprise a frame having a reference surface, a carrier coupled to the frame and configured to translate relative to the frame, a dimension measurement system coupled to the carrier and having a thread contact element configured to translate relative to the frame and orthogonally the translation axis of the carrier. The dimension measurement system configured to determine thread dimensions relative to the frame reference surface.

An inductive sensor device (23) having a scale unit (24) and a sensor unit (25) that can be moved relative to each other in a measuring direction (M) is described. The scale unit contains scale elements (26) that are adapted to create a field pattern (P(x)) in measuring direction (M) that is detected by means of a receive circuit (35) of the sensor unit (25). The receive circuit (35) contains at least a first receive coil set (36) and a second receive coil set (37) that are offset in measuring direction (M). In so doing a first spatial phase and a second spatial phase receive signal is provided by these receive coil sets (36, 37) respectively. These spatial phases can be used for absolute position determination.

Describes is a feed mechanism for a slider which is convenient to use with good durability and low costs by eliminating a rack-and-pinion method. The feed mechanism allows the slider to be fed and moved along a longitudinal main scale. The feed mechanism includes a driving gear that is a gear train pivotally supported by the slider, a driven roller that meshes with the driving gear and rotates by rotation of the driving gear, and an arm that includes a cup portion capable of receiving the driven roller on a distal end. The arm includes the cup portion capable of receiving the driven roller on the distal end and is pivotally supported by the slider on a base end. The cup portion in a state of receiving the driven roller is biased toward the main scale by a pin plunger. Accordingly, the driven roller is kept abutted against the main scale.

In addition to other aspects disclosed, a caliper is configured to measure at least one physical dimension. The caliper has a display configured to present a first representation and a second representation of a measurement provided by the caliper. The format of the first representation is different from the format of the second representation, and the first representation is approximately simultaneously displayed with the second representation.
