Technical Specifications

  • Channel:Dual, isolated between channels
    Amplitude: Adjustable 0 - 80 mA peak into 500 ohm load each channel .
  • Output Voltage: 0 - 40V (load 500 ohm)
  • Waveform: Asymmetrical biphasic square pulse
  • Pulse Rate: Adjustable 2-150 pulses per sec. (Hz)
    Pulse Width: Adjustable 50-300 µS
  • Modes: Normal, Burst, Modulated Rate & Width, Strength Duration, Bi-Pulse. Burst Mode—7 pulses per burst, 2 bursts per second, with a fixed pulse rate of 100 Hz. (Only pulse width is adjustable). Normal Mode—provides continuous train of pulses with no variation or modulation of set pulse rate and width (Pulse rate and pulse width are fully adjustable). Modulated Rate & Width (MRW)—during the beginning of the first 0.5 second period, the pulse width is automatically decreased to 50% of its original setting and then during the 0.5 second period, the pulse rate is decreased to 50% of its original setting (Pulse rate and width are fully adjustable). Strength Duration (SD)—consists of alternating modulated intensity and pulse width, so that the intensity is always increasing when the pulse width is decreasing, and vice-versa. Amplitude is modulated to 62.5% of maximum setting (width equal to setting), and pulse width modulates to 67% of setting (amplitude equal to setting). Total cycle time 6 seconds (Pulse rate and width are fully adjustable). Bi-Pulse—provides endorphin release effect and gate control pain-blocking effect from both channels at the same time, respectively. Channel 1 delivers a fixed pulse rate of 4 Hz, while Channel 2 delivers a fixed pulse rate of 100 Hz. Stimulation is burst on for 1 second, then off for 1 second.
  • Patient Compliance Timer: Records the last 60 individual treatment sessions, with up to 999 minutes per session, and can record the whole treatment time for all the cumulative sessions.
  • Treatment Timer: Adjustable 5 - 90 minutes in 5 minute increments, or continuous
  • Power Supply: One 9-volt battery (heavy duty, alkaline, or rechargeable)
  • Size: 10 x 5.9 x 2.4 cm
  • Weight: 130 grams with battery
