<P>PROBLEM TO BE SOLVED: To provide radio equipment for automatic meter reading for matching a radio frequency with an actual frequency, and for confirming communication in a normal installation state, and for outputting the mean value of the strength of reception radio signals when the quiescent time of a radio output is absent, and for confirming the normal end of radio communication by a dial operation. <P>SOLUTION: A master device is provided with a reset switch, a function switch, a channel switch, a maintenance calling switch and an alliance switch. A slave device is provided with a reset switch, an alliance switch, a channel switch and a function switch. In the case of the alliance of the master and the slave device in the installation construction, a microcomputer converts an RSSI value as the strength of a reception radio signal from an analog value to a digital value, and digitally performs averaging processing or the like, and for outputting the RSSI value as an analog value, and for confirming radio communication installation conditions between the master device and the slave device by making the master device and the salve device operate in a fixed time. <P>COPYRIGHT: (C)2008,JPO&INPIT |
