Graham Field TENS Unit Analog Tens with Timer T.E.N.S. (Transcutaneous Electrical Nerve Stimulation) is indicated under a physician's prescription for the symptomatic relief and management of chronic (long-term) pain and the treatment of post-operative or post-traumatic pain. Features Dual channels Three modes: Standard, Burst, Modulation Includes: TENS unit, molded carrying case, instructions and accessories (four electrodes and lead wires) Modulation Mode: Pulse width is automatically varied in a cyclic pattern over an interval of nominally 5.0 seconds maximum. Pulse width decreases linearly over a period of 1.5 seconds from the control setting value to a value which is decreased 45% maximum. The narrower pulse width will continue for 2 seconds maximum, then increase linearly over a 1.5 second period to its original value. The cycle is then repeated Burst Mode: Bursts consist of 9 & 2 pulses at maximum pulse rate. Bursts occur twice every second Specifications: Brand: Graham Field Product Type: TENS Analog Required (not included): One 9-Volt alkaline battery Channels: Dual Pulse Amplitude: Adjustable, 80 mA peak maximum for positive pulse or -20 mA peak maximum for negative pulse into 500 ohm load each channel Pulse Width: (Adjustable) 40 - 260 microns
