摘要： A host apparatus collects the physical or chemical quantities of articles, which have been measured by a plurality of measuring devices, for example, vernier calipers. Each calipers has a caliper unit as a measuring means, a dip-switch, a CPU, a RAM, and a transmitter. The caliper unit has an analog-to-digital (A/D) converter. The dip-switch is operated, thus setting an ID number of the device, before the device is used. The ID number is stored into the RAM. When the transmission button of the device is pushed, the CPU edits the digital value supplied from A/D converter and the ID number stored in the RAM, thereby forming a serial-data message. This message is transmitted by a transmitter, in the form of a radio message. The host apparatus has a receiver and a host computer. The receiver received the serial-data messages transmitted from the measuring devices. The host computer collects the values measured by the devices and contained in the serial-data messages, in accordance with the ID numbers also contained in the serial-data messages.

摘要： At the start of measurement by a length measuring device, a calibration coil in which the temperature characteristics are known, is connected to an oscillator. The oscillation frequency of the oscillator at this time is counted by a counter and is given to microcomputer. Microcomputer obtains temperature information corresponding to counted numbers with reference to a table of counted numbers versus temperature information which has already stored temperature information corresponding to a plurality of counted numbers and stores the obtained temperature information in a data storage area. In measurement mode, measured values subjected to temperature compensation are obtained according to the temperature information stored in the data storage area.

摘要： An oscillator oscillates at a frequency determined by the distance moved by a probe. The probe in contact with an object under measurement, moves according to the displacement of the object. A controller computes the distance moved by the probe from a reference position at predetermined time intervals by using the shift of the oscillating frequency of the oscillator. The controller further decides if the computed distances are within a predetermined range. If the computed distances moved are within that range, the controller supplies the computed distance moved to a transmitter, which in turn wirelessly transmits the distance. When the computed distance moved is outside the predetermined range, the controller does not output the distance moved to the transmitter, nor does it supply the distance moved every four computations of the distance moved.
