Tens 7000 Product Description and Review

The TENS 7000 may be a handheld, portable pain control device, but don’t let its conveniently small size fool you. This unit is chock full of features and functions, front and back and top to bottom. From the top you can see a knob cover, and four different channels (two on/off and amplitude controls, and two output receptacles). The front panel includes an amplitude knob, a battery indicator, a channel output, a timer (those three on the LCD screen), an increase button, a decrease button, and a set bottom, all on the left. On the right, the screen shows the mode, and pulse rate and width; then there are the mode button and a lid cover.
And there’s still more. The back panel features a belt clip and the battery cover. Going back to the top, the knob cover keeps the amplitude controls out of reach so you won’t accidentally reset the output while using the TENS 7000. Similarly, the lid cover encases the mode, set, increase and decrease buttons. There is the possibility that your doctor presets the controls for you, and asks you to keep the lid closed. However, you can decrease the intensity level should it ever become uncomfortable. The amplitude controls govern the levels of stimulation intensity.  

The increase button, easily identifiable by its triangle shape, is used to increase the pulse width and rate, as well as the timer. Conversely, the decrease button is shaped like an inverted triangle, and its purpose is to reduce the pulse width and rate and the timer. The round mode button on the right allows you to switch between the five different stimulation modes. These modes are burst, normal, modulated rate and width, strength duration, and bi-pulse. The set button (also round but on the middle of the front panel) adjusts the rate, width and timer parameters.

Once you have entered the desired settings, they will be displayed on the LCD screen. Pulse rate and width are shown on the screens’ middle-right, as are the timer and clock icon; the modes are visible on the top of the liquid crystal display, and the channel output on the left for channel 1, and the right for channel 2. These are only the exterior parts of the TENS 7000 unit. They are all used together to manipulate the electrical current that travels through the electrodes, and which ultimately delivers the pain relief that is the crux of this device.
