A pair of clips which plug directly into the Folsom and ErosTek power units.
Each clip is a complete 2-electrode circuit, with one electrode on each side of the clip. Both clips can be used with the Folsom or ErosTek boxes, using both of the two channels.
The jaws of the clips are smooth metal, designed to be clipped directly onto the skin. These clips are not designed to be clipped onto other metal items, and the channel should not be turned on while the electrodes are closed, since that will only short the circuit without producing any stimulation, while draining your battery and possibly damaging your signal generator.
