Usage Instructions
- Connect Lead Wire: Plug the 4mm banana plug of your ECG lead wire into the adapter's banana socket.
- Attach to Electrode: Clamp the alligator clip firmly onto the target ECG electrode (ensure full contact with the conductive surface).
- Verify Connection: Check that the clip is secure and the socket is tightly fitted before initiating ECG monitoring.
- Post-Use: Disconnect the adapter, clean the clip with mild disinfectant, and store in a dry place.

FAQ
Q: Can this adapter work with 3mm banana plugs?
A: No-it is specifically designed for 4mm banana plug ECG lead wires. We also have the adapter for 3mm Din plugs.
Q: Is the alligator clip suitable for all ECG electrode types?
A: It works with standard flat-surface ECG electrodes (ensure the clip grips the conductive area).
Q: Can the adapter be autoclaved?
A: No-clean with a mild disinfectant cloth (do not autoclave or soak).
