FADOS7F1-18V [New Version] Fault Detector and Oscilloscope

The FADOS7F1-18V [New Version] combines seven essential electronic testing functions in one compact diagnostic instrument. Designed for electronics technicians, repair professionals, automotive specialists, engineers, and maintenance teams, it makes circuit-board troubleshooting faster, clearer, and more reliable.

Using VI Curve Testing and Analog Signature Analysis, the device can help identify abnormal electronic components without requiring immediate power-up of the circuit under test. Compare test signatures, review saved measurements, and record board test results with photographs for accurate documentation.



The built-in PC oscilloscope, voltage and current measurement functions, component threshold display, and programmable square-wave output make the FADOS7F1-18V a versatile solution for PCB repair, ECU diagnostics, industrial electronics testing, and laboratory use.
