Technical Specifications of TENS 7000

Mechanism               Technical Description
Channel                                       Dual, isolated between channels
Pulse Amplitude                 Adjustable, 0-100mA at 500ohm load each channel
Wave Form                                Asymmetrical Bi-Phasic Square Pulse
Voltage                                                0-50V (Load: 500ohm)
Power Source                                            One 9 Volt battery
Size                                               10.1cm(L)x6.1cm(W)x2.45cm(H)
Weight                                                        150 grams with battery
Pulse Rate                                   Adjustable, from 2 to 150 Hz, 1Hz/step
Pulse Width                    Adjustable, from 50 to 300microseconds, 10microseconds/step
Modes                        B(Burst), N(Normal), M(Modulation), SD1(Strength Duration), SD2
Burst Mode                                     Burst rate: Adjustable, 0.5-5Hz
                                                Pulse width adjustable, 50-300 microseconds
                                                              Frequency fixed = 100 Hz
Normal Mode            The pulse rate and pulse width are adjustable. It generates
                                           continuous stimulation based on the setting value
Modulation Mode            A combination of pulse rate and pulse width modulation.
                                      The pulse rate and width are automatically varied in a cycle pattern.
                                        The pulse width is decreased by 50% from its original setting in
               0.5 seconds, then the pulse rate is decreased by 50% from its original setting in 0.5 seconds.
                                    Total cycle time is 1 second. In this mode, pulse rate (2-150Hz) and
                                            pulse width (50-300 microseconds) are fully adjustable.
SD1 Mode                 The SD1 mode consists of automatic modulation intensity and pulse width in 40% range. The intensity is always increasing while the pulse with is decreasing and vice verse. The intensity decreased by 40% while the pulse width is increased by 40% in 5 seconds. In the next 5 seconds, the intensity is increased by 40% while the pulse width is decreased by 40%. Total cycle time is 10 seconds. Pulse rate (2-150Hz) and pulse width (50-300 microseconds) are fully adjustable.
SD2 Mode                    The SD2 mode consists of automatic modulation intensity and pulse width in
70% range. The intensity is always increasing while the pulse with is decreasing and vice verse. The intensity decreased by 70% while the pulse width is increased by 70% in 5 seconds. In the next 5 seconds, the intensity is increased by 70% while the pulse width is decreased by 70%. Total cycle time is 10 seconds. Pulse rate (2-150Hz) and pulse width (50-300 microseconds) are fully adjustable.
Timer                     Adjustable, from 1 to 60 minutes of continuous. Adjustable in 1 minute each step from 1 to 15 minutes and 5 minutes each from 15 to 60 minutes. Treatment time countdowns automatically.
Patient Compliance Meter          This unit can store 60 sets of operation records. Total recorded
                                                                                   time is 999 hours.
Low Battery indicator        A low battery indicator will show up on the LCD when the battery is low
Operating Conditions            Temperature: 0-40˚C | Relative Humidity: 30%-75% | 
                                                             Atmospheric pressure: 700Hpa-1060Hpa
Remark                     There may be a +/-5% tolerance of all parameters and +/-20% tolerance 
                                                                      of  amplitude and voltage
