<P>PROBLEM TO BE SOLVED: To provide a radio master unit used in a radio telemeter system which can reduce operation time in a radio wave measurement mode. <P>SOLUTION: A radio master unit 1 includes a radio wave measurement mode used in a radio telemeter system. The radio wave measurement mode includes both of an emission mode that the radio master unit itself emits a radio wave to perform a radio wave measurement, and a receiving mode to monitor a channel that performs another radio wave measurement except for a channel emitting in the emission mode. Further, the radio wave emission mode is terminated when a radio wave emission is sensed by a channel different from the channel emitting in the receiving mode. <P>COPYRIGHT: (C)2013,JPO&INPIT |
