たことを特徴とするクラスターケーブル試験器。[Scope of claim for utility model registration] A cluster cable tester that tests the condition of a cluster cable whose both ends are connected to connection terminals, which includes a power supply, an ammeter, a reverse current blocking diode, and an LED.
If all the cables in the cluster cable are properly connected and conductive, only the ammeter will work, and if all the cables in the cluster cable are conductive but one of them is incorrectly connected. The cluster cable tester is characterized in that a circuit is configured such that only the LED operates when the cluster cable is disconnected, and neither the ammeter nor the LED operates when any of the cables in the cluster cable is disconnected.
