- Insulated wire clamp: designed for use with a 4 mm banana plug cable (not included). Press the handle forward to clamp the wire for electrical testing. - Test probe clips: ends feature a standard 4 mm socket, allowing connection to test leads and devices as well as test hook clips. - Connection cable for clamp test tip: the side provides a standard 4 mm socket that can be plugged directly into a banana plug or circuit tester. - Electric test probes: a flexible test probe usable with instruments and measuring devices such as oscilloscopes, offering high sensitivity and high reliability. includes the connection cable of the clamp test probe. Use scenarios: - Troubleshooting a power supply: clamp a wire with the insulated clamp, connect test leads via the 4 mm socket, and probe with a scope to observe waveforms. - Electronics debugging on a PCB: attach test probe clips to signals or test points, using the 4 mm socket to connect to measurement devices and hook clips as needed. - Circuit verification in harnesses: use the 4 mm socket connections to link to banana plugs or circuit testers, then monitor signals with a flexible probe for quick checks.
