A measuring instrument includes a main body casing, a detector on the main body casing and detecting an amount of stylus head displacement, a display on an outer surface of the casing; a plurality of key switches on the outer surface, a menu proximate the display on the outer surface, and a display controller controlling the display. The display includes a main display and a cursor display, which is arranged in a location alongside the menu and displays a cursor pointing to the menu, and performs control such that a measured value based on an amount of displacement is displayed, but the cursor is not displayed when in a measurement mode where the detector detects the amount of displacement, and such that a cursor is displayed so as to point to the menu corresponding to a selected menu when in a settings mode where measurement conditions are set.

An electronic device includes a communication device and a processor. The processor receives sensor kind information via the communication device from one of at least one sensor or an electronic measurement instrument to which the at least one sensor is connected, transmits the received sensor kind information to a database storing a combination of a sensor kind and a measurement mode in which measurement contents are defined, acquires, from the database, the measurement mode in accordance with the transmitted sensor kind information, and sets the acquired measurement mode corresponding to one of the at least one sensor or the at least one sensor connected to the electronic measurement instrument.

A graph display method, wherein a first graph corresponding to a first mathematical expression is displayed on a display, and when an operation to input, as a modified expression of the first mathematical expression, a third mathematical expression having a notation different from that of the first mathematical expression is accepted, and a third graph corresponding to the third mathematical expression is displayed on the display, the third graph is displayed on the display in a way of displaying, the way being different depending on whether a condition that the first mathematical expression is mathematically identical to the third mathematical expression is satisfied or not.

There is provided a data processing apparatus including a processor, the processor is configured to: receive one or more sets of data output from at least one data output apparatus via a communication network, each set of the data including sensor data obtained by at least one sensor and first specifying information that specifies the data processing apparatus; determine whether or not the first specifying information included in the received one or more sets of data satisfies a predetermined condition; classify the one or more sets of data determined to satisfy the condition into a same group; and generate and output an output file based on the one or more sets of data classified into the same group.

Systems and methods for compressing high-frequency signals are described in certain embodiments herein. According to certain embodiments, a high-frequency signal can be converted into a lower frequency signal so that it can be processed by one or more devices in a lower frequency infrastructure. In certain embodiments, the high-frequency signal can be compressed by certain signal conditioning components and an algorithm executed by a computer processor to at least receive a high-frequency signal, correct the high-frequency signal, determine a number of samples to be taken from the high-frequency signal (i.e., sample the high-frequency signal), store a value associated with the sampled signal, and generate a waveform that includes lower frequency content that may represent the original, high-frequency signal.
