Abstract

PURPOSE:To investigate a grounding accident point easily at any time, by providing a function of performing in-operation display for a prescribed time on detecting a pulse current and of increasing the luminous intensity of an indication part. CONSTITUTION:A gate signal generator 14 detects the initial point of a signal passed through an antenna 5 and an amplifier 9 to generate an opening signal for a series of gates. Consequently, an operation display device 16 operates for a prescribed time to show that a receiver 6 is normal. Further, an indication-part illuminating instrument 15, when the power switch of the receiver 6 is turned on, decreases in luminous intensity and also increases in luminous intensity enough to read an indication on a detection member 13 by the signal from the gate signal generator 14. Consequently, the operation display device 16 shows whether the receiver 6 is in normal operation or not, and the detection meter illuminating instrument 15 makes the indication on the detection meter 13 easy to read.
