Abstract

PURPOSE: To indicate a wire number, by connecting wires and terminals to an input circuit of a matrix circuit and connecting output circuit to an indicator and coupling a part of workman's body to a power source and bringing his finger into contact with a wire.
CONSTITUTION: The output of the matrix circuit 1, which performs BCD convertion, is binary-coded and then entered into an amplifier 2. The output of the amplifier is applied to an indicator tube driving decoder 3, thereby changing the binary output into a decimal output. The decimal output is entered into indicator to indicate the wire number. A constant-voltage DC power source 5 is used to supply power to each appliance and connected to the workman. Plugs 8 for bundled wires 7 coupled to the input side of the matrix circuit 1 are connected to plug receptables 10 of an electric appliance 9 to be worked. When the finger of the workman comes into contact with a wire, the wire number is displayed on the indicator.
