The Gossen Metrawatt METRAFUSE FD PRO is a test instrument used for the speedy identification of which fuse or circuit breaker is protecting circuit. The METRAFUSE FD PRO consists of two parts: a receiver and atransmitter.The transmitter is connected to the circuit under test and uses theAC circuit’s power to generate and inject a modified high frequency signal into the live conductor. The signal will not adversely affect other equipment but is powerful enough to work over cable runs of several hundred meters. The receiver is used to detect the signal from the transmitter at the distribution board. When its scanning tip is put in contact with the fuse or circuit breaker that is connected to the circuit under test, the receiver will indicate the presence of the transmitter signal both by LED and beeping.
