How to Connect TENS Lead Wires to Your Electrodes

Quick answer

Connect the lead wire's pin connector to the electrode's tab, then snap the wire into the device port. Ensure a snug fit to avoid intermittent stimulation.

Step-by-step connection guide

1. Step 1: Check the electrode tab: Make sure the electrode pad has a clean, dry tab. Do not touch the adhesive side. Peel the backing and place the pad on clean skin before attaching the wire. Dirty or oily tabs can prevent a secure snap connection.
2. Step 2: Insert the pin connector: Hold the lead wire by the molded connector body. Push the metal pin straight into the electrode tab until you hear or feel a click. Avoid bending the pin. A bent pin can break the connection. If it does not click, try a different electrode.
3. Step 3: Connect the wire to the device: Plug the other end of the lead wire into the TENS device port. Push firmly until it seats fully. Do not twist or force it. A partial insertion can cause the wire to fall out during movement.
4. Step 4: Test the circuit: Turn on the device at a low intensity. If you feel no sensation or the device shows an error, check each connection. Re-seat the wire at the electrode and device. Intermittent buzzing or no output usually means a loose pin connection.
