RADIO METER-READING SYSTEM

摘要

PROBLEM TO BE SOLVED: To prevent a button for radio meter-reading and a button for visual meter-reading which are shown on a displaying part of a master unit from being mistaken for each other in a radio meter-reading system which performs remote meter-reading of a meter. SOLUTION: A controlling part 8 of a master unit 1 contains a meter-reading propriety deciding means that decides whether or not meter-reading through radio communication can be performed with a meter 3 connected to a slave unit 2 and a display controlling means which shows only a button that selects meter-reading start of the meter through radio meter-reading on a displaying part 6 when the decision result shows that the meter-reading is possible and also shows a button that selects visual meter-reading start when it fails in radio communication the defined number of times.
