Abstract: An automatic measuring device includes a micrometer including a spindle that moves forward and backward to be brought into contact with or away from a workpiece and a displacement detector unit that detects displacement of the spindle, and an automatic operation unit that automates the forward and backward movement of the spindle by power. The automatic operation unit performs a first forward-movement step of moving the spindle forward to bring the spindle into contact with the workpiece, and a contact determination step of determining the contact between the spindle and the workpiece in the first forward-movement step. In the contact determination step, the spindle is determined to be in contact with the workpiece when a change in a position of the spindle detected by the displacement detector unit in the first forward-movement step becomes equal to or less than a predetermined contact determination threshold.

Abstract: There is provided a method for controlling a small-sized adjustable measuring force measurement device capable of appropriately setting the origin.
A central control unit changes an operation mode to an origin setting mode in response to predetermined mode changing operation. The central control unit sets a counter value of an encoder to zero as an origin when a measuring force detecting means detects that a movable member is brought into contact with an object to be measured at a predetermined pressure in the origin setting mode.-

Abstract: A digital measurement instrument with excellent environmental durability and at least a conventional level of usability including a main scale, a slider movable relative to the main scale, a displacement sensor configured to detect displacement or position of the slider in relation to the main scale, and a control circuit. The control circuit controls change between a normal measuring mode and an origin setting mode. The control circuit also sets and stores a first area, the first area being a preset predetermined range outside of a measurement range. The control circuit also changes operation mode from the normal measuring mode to the origin setting mode when the slider is detected to have stopped within the first area for a consecutive predetermined period of time. Additionally, the digital calipers are provided with no mechanical push button switches.

Abstract: A deformation detection apparatus includes a cell movement-control assembly to handle a linear motion and a rotational motion of a battery cell, a body that supports the cell movement-control assembly, a digital micrometer, and control circuitry. The control circuitry controls a displacement of the battery cell between a first position and a second position along a longitudinal axis through a scanning region of the digital micrometer and a plurality of rotational positions of the battery cell at a plurality of charge states and a plurality of discharge states. The control circuitry measures a plurality of outer diameter values of the battery cell for a plurality of linear positions and a plurality of rotational positions along the longitudinal axis of the battery cell and determines a change in a geometrical shape (deformation and/or strain) of the battery cell for the plurality of linear positions and the plurality of rotational positions.

Abstract: The invention relates to a handheld measurement instrument and a configurator forming a measurement kit. The measuring instrument and the configurator are provided each with an interface, enabling communication between the measuring instrument and the configurator. The handheld measurement instrument further comprises a measuring unit for measuring distances or angles of an object by contacting physically distinct points of said object; and a circuit unit applying a function of a functionality on electronic signals/electronic measurement results delivered from the measuring unit in order to deliver the measuring results in a desired form to the user by output means. The form the results should be presented can be selected by the user using input means of the measuring instrument. The circuit unit is configurable by the user using the configurator in order to determine, with which functionality the circuit unit and the input means, respectively should be equipped.

Abstract: A calibration control device for being coupled to a measuring device such as a caliper, micrometer, or gauge is provided. The calibration control device includes a circuit portion and couples to a coupling feature on the measuring device. A calibration limit portion defines a parameter limit as related to a usage limit for which the measuring device is certified as calibrated. A controller operates a host-side data connection portion of the calibration control device to output measuring data in a first mode when the usage limit is not exceeded, and operates the calibration control device to perform a calibration limit function when the usage limit is exceeded. The calibration limit function may include stopping the output of the measuring data through the host-side data connection or providing an out-of-calibration warning to the host, or the like.
