08

Pulse Rate

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

21

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

22

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.

23

Patient Compliance Meter

This unit can store 60 sets of operation records. Total recorded time is 999 hours.

24

Low Battery Indicator

A low battery indicator will show up when the battery is low.

25

Operating Condition

Temperature:0℃~40℃
Relative Humidity: 30%~75%
Atmosphere Pressure : 700Hpa~1060Hpa

26

Remark
