The P.E.S. Power Box is an example of a box specifically made to use for sexual electro stimulation play. It is not a relabeled TENS, EMS, or other NMES type device that has been repurposed.
Transcutaneous electrical nerve stimulation (TENS) is the use of electric current produced by a device to stimulate the nerves for therapeutic purposes.
Electrical muscle stimulation (EMS), also known as neuromuscular electrical stimulation (NMES) or electromyostimulation, is the elicitation of muscle contraction using electric impulses.
An Electrode with only one connection point and one continuous conductive surface. This device must have another Electrode used with it to complete the circuit. It will not work if connected all by itself. (Exception to this rule is if it is used in a Three-Electrode Configuration on a P.E.S. Power Box.) Also known as Uni-Polar.
An Electrode with two connection points and two separate conductive surfaces encapsulated within the same Electrode. This device can be used by itself as it can complete its own circuit. This device can also be used as a single pole Electrode when only one of its connection points is used. Also known as Bi-Polar.
An Electrode with three connection points and three separate conductive surfaces encapsulated within the same Electrode. This device can be used by itself (on a P.E.S. Power Box) as it can complete its own circuit. It can also be used as a single- or double-pole Electrode depending on how many of its Connection Points are used. Also known as Tri Polar.
An Electrode with four connection points and four separate conductive surfaces encapsulated within the same Electrode. This device can be used by itself as it can complete its own circuit. It can also be used as a single-, double-, or triple-pole Electrode depending on how many of its Connection Points are used. Also known as Quad Polar.
~ONE ELECTRODE CONFIGURATION
This is one of the most basic placements. You need a double pole (bi-polar) Electrode to create this placement. Because these Electrodes can be used singly; you will not need a second Electrode to complete the circuit.
~TWO ELECTRODE CONFIGURATION
This allows you to spread your stimulation between two separate areas of the anatomy. To create this configuration you can use either two single pole (uni-polar) Electrodes, two double pole (bi-polar) Electrodes used as single pole Electrodes, or a single pole Electrode with a double pole Electrode being used as a single pole Electrode.
~THREE ELECTRODE CONFIGURATION
With a P.E.S. Power Box, this is your most versatile Configuration. To create this Configuration, you can use three single pole Electrodes or a double pole Electrode with a single pole Electrode. This configuration can be comprised of any combination of Electrodes, either double or single pole.
Just keep in mind these basic rules of thumb:~FOUR ELECTRODE CONFIGURATION
a) you must have a complete circuit on either Channel A or Channel B for the incomplete circuit on the remaining channel to work;
b) you typically want your complete circuit to run between the two Electrodes furthest apart with the middle Electrode on the incomplete circuit;
c) finally, a true Three-Electrode Configuration is always made using THREE of your four Connections.This Configuration allows you to play with the sensations in an additional manner. After you have found the settings on your P.E.S. Power Box most pleasing to you, you can use the Power Interrupt for Channel A and Channel B to alter the flow of the stimulation between the two Channels. This configuration may only be possible with a P.E.S. Power Box.
You use all four connection points. Typically comprised of two double pole Electrodes, four single pole Electrodes, or a combination of single and double pole Electrodes. Sometimes this is not the most effective configuration as it can spread your stimulation over too wide an area thus reducing the intensity of your sensations.
