Claims (1)
表示器を有する電界強度デジタル表示装置において、該
電界強度が任意の設定値よりも大きい場合は該表示器に
該電界強度をそのまま表示させる信号を供給し、該電界
強度が任意の設定値よりも小さい場合は該表示器に電界
強度が零に等しいころを表示させる信号を供給する制御
回路を設けた電界強度デジタル表示装置。In a field strength digital display device having a display device that displays a digital value of the field strength of a received high frequency signal, if the field strength is larger than an arbitrary set value, a signal is sent to the display device to display the field strength as it is. A field strength digital display device comprising: a control circuit for supplying a signal that causes the display to indicate that the field strength is equal to zero when the field strength is smaller than an arbitrary set value.
