ABSTRACT:
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.
