TENS : Durable, ergonomic, as always, a potent defense against pain, the Ultima 3 is a great defense against pain. Just remove the sleek black unit from its professional case, insert the battery, apply the electrodes, and plug in the lead wires. Turn on the unit to adjust the pulse width (how strong the current is) and the frequency (how many times the current is delivered over time) and you can enjoy a pain free day while you take it anywhere you go! TENS stimulates sensory nerves to block pain signals, stimulate endorphin production to help normalize sympathetic function and has a biphasic, low volt current.

Technical Specifications

Output: Two independent output terminal.
Wave Form: bi-phasic square waves with zero net direct current (DC) component.
Amplitude: 0-80mA each channel, adjustable (500 ohm load)
Pulse Width: 50 to 260 microseconds, adjustable.
Frequency: 2 to 150 Hz, adjustable.
Charge per Pulse: 80mA x 250 microseconds (500 ohm test load)
Maximum Voltage: 0 to 80 volts.
Maximum Charge: 20 microcoulombs per pulse maximum, positive pulse and negative pulse seperate.

Function:
(1)Burst: 7 pulses per burst, 2 bursts per second, 100Hz fixed frequency.
(2)MRW: Pulse rate and pulse width show alternating periodic change, For example, if pulse rate and pulse width are set to maximum respectively, when the pulse amplitude is changed from 150-75Hz decreasing, pulse width would be changed from 130-260 us increasing, at period 1 second.
(3)SD: Pulse rate and pulse width show alternating periodic change, For example, if pulse rate and pulse width are set to maximum respectively, when the pulse amplitude is changed from 40-30 volts decreasing, pulse width would be changed from 175-260 us increasing, at period 6 seconds.
(4)Bi-Pulse: Channel 1 fixed output pulse rate at 100Hz, Channel 2 fixed output pulse rate at 4Hz. Continuously output for 1 second and then stop output for 1 second, complete cycle at period 2 sec.
(5)Normal: Continuous output with adjustable amplitude, pulse rate, pulse width.
