This signal tracer /injector has been designed to inject or detect a specific signal into an audio circuit in need of repair (such as amplifiers, radios, tone controls, ...) so as to detect the fault. In this way problems can be traced more easily. The signal tracer may also be used as a simple monitor or amplifier.

Build your own component tester and receive all useful information about resistors, diodes and many more. Auto shut-down. Shows Pin-out.

This K8118 detector converts imperceptible noise for humans such as bat signals into audible noise. Another usage may be the early detection of possible failures in machines, engines and electronics. The stereo feature adds the possibility to pinpoint the source.
