Four-Channel Digital TENS/EMS COMBO
• Precise Intensity Control – There are 100 steps of intensity level controlled by press buttons from 1 to 100mA.
• Press Button Control – The power, intensity level and parameter are controlled by press buttons, which is easy for the users to adjust the settings. All of the buttons are protected by a swing door to avoid accidental touch.
• Large Liquid Crystal Display – A large LCD in 6.1 x 4.4 cm showing the intensity level, settings and treatment timer. The selected modes and parameters are readable.
• Two Treatment Timers – There are two individual timers controlling the output of CH1, CH2 & CH3, CH4. This function is ideal when two patients accept treatment with the same machine.
• Treatment Time Countdown – The output will shut off automatically when time is up.
• Compliance Meter – The unit can store 60 sets of record of operation.
• Health Canada Licensed Device
Channel: Four, isolated between channels
Pulse Amplitude: Adjustable, 0-100 mA peak into 500 ohm load each channel.
Wave Form: Asymmetrical Bi-Phasic Square Pulse
Voltage: 0 to 50V (Load: 500 ohm)
Power source: Four 1.5V AA batteries or AC Adaptor
Size: 13.8cm(L) x 7.8cm(W) x 2.8cm(H)
Weight: 425 grams with battery
Pulse Rate: Adjustable, from 2 to 150 Hz, 1 Hz/step
Pulse Width: Adjustable, from 50 to 300 microseconds, 10 µs/step
On Time: Adjustable, 2~90 seconds , 1 Sec./ step
Off Time: Adjustable, 0~90 seconds , 1 Sec./ step
Ramp Time: Adjustable, 1~8 seconds, 1 Sec./ step, The “On” time will increase and decrease in the setting value.
Mode: Five TENS Modes: B(Burst), N(Normal),M (Modulation), SD1 (Strength Duration), SD2
Three EMS Modes: C(Constant), S (Synchronous), A(Alternate),
Burst Mode(B): Burst rate: Adjustable, 0.5 ~ 5Hz, Pulse width Adjustable from 50~300µs, Frequency fixed = 100 Hz
Normal Mode(N): The pulse rate and pulse width are adjustable. It generates continuous stimulation based on the setting value.
Modulation Mode(M): Modulation mode is 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 second, then the pulse rate is decreased by 50% from its original setting in 0.5 second.Total cycle time is 1 second. In this mode, pulse rate(2-150Hz) and pulse width(50-300µs) are fully adjustable.
SD1 Mode: The SD1(Strength-Duration) mode consists of automatic modulation intensity and pulse width in 40% range. The intensity is always increasing while the pulse width is decreasing and vice-versa. The intensity is 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 (50~300µs) are fully adjustable.
SD2 Mode: The SD2(Strength-Duration) mode consists of automatic modulation intensity and pulse width in 70% range. The intensity is always increasing while the pulse width is decreasing and vice-versa. The intensity is 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 (50~300µs) are fully adjustable.
Constant Mode (C): Constant stimulation based on setting value. Only pulse width, pulse rate and timer are adjustable in this mode. “Constant” is equal o the”Normal” mode of a TENS unit.
Synchronous Mode (S): Stimulation of both channels occurs synchronously. The “ON” time including “Ramp Up” and “Ramp Down” time. Therefore, the setting of ON Time should be no less than two times of the “Ramp” time in this mode. ON TIME ?Ramp up + Ramp down
Alternate Mode(A): The stimulation of the CH2 will occur after the 1st contraction of CH1 is completed. In this mode, the setting of ON Time should be no less than two times of the “Ramp” time. The OFF Time should be equal or more than the ON Time. ON TIME > Ramp up + Ramp down OFF TIME ? ON TIME
Timer: Two Adjustable timers, from 1 to 60 minutes or Continuous. Adjustable in 1 minute each step from 1 to 15 minutes, and 5 minutes each step from 15 to 60 minutes. Treatment time countdown 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 when the battery is low.
Operating Condition: Temperature:0C~40C
Relative Humidity: 30%~75%
Atmosphere Pressure: 700Hpa~1060Hpa
Remark: There may be up to a +/-5% tolerance of all parameters and +/-20% tolerance of amplitude & voltage.
Included: 1 x 4-Channel Unit, 4 x AA Batteries, 4 x Lead-wires, 1 x AC Adapter, 2 x 4 pcs electrodes, Operation Manual, and Carry Case.
