• Model #: EV-906
  The EV-906 Digital TENS/EMS is a battery operated pulse generator that sends electrical impulses electrodes to the body and reach the nerves and underlying muscle group. This unit is a combination stimulator of TENS and EMS which can be used for muscle stimulation and pain relief. The device is provided with four controllable output channels, each independent of each other. An electrode pair can be connected to each output channel. The intensity level is controlled by press buttons.

  MECHANISM TECHICAL DESCRIPTION 01 Channel Four, isolated between channels 02 Pulse Amplitude Adjustable, 0-100 mA peak into 500 ohm load each channel. 03 Wave Form Asymmetrical Bi-Phasic Square Pulse 04 Voltage 0 to 50V (Load: 500 ohm) 05 Power source Four 1.5V AA batteries 06 Size 13.8cm(L) x 7.8cm(W) x 2.8cm(H) 07 Weight 425 grams with battery 08 Pulse Rate Adjustable, from 2 to 150 Hz, 1 Hz/step 09 Pulse Width Adjustable, from 50 to 300 microseconds, 10 μs/step 10 On Time Adjustable, 2~90 seconds , 1 Sec./ step 11 Off Time Adjustable, 0~90 seconds , 1 Sec./ step 12 Ramp Time Adjustable, 1~8 seconds, 1 Sec./ step, The "On" time will increase and decrease in the setting value. 13 Mode Five TENS Modes: B(Burst), N(Normal),M (Modulation), SD1( Strength Duration), SD2 Three EMS Modes:C(Constant) S (Synchronous), A(Alternate) 14 Burst Mode(B) Burst rate: Adjustable, 0.5 ~ 5Hz Pulse width adjustable, 50~300μs Frequency fixed = 100 Hz 15 Normal Mode(N) The pulse rate and pulse width are adjustable. It generates continuous stimulation based on the setting value. 16 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. 17 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. 18 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. 19 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. 20 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
