Technical Specifications for Transcutaneous Electrical Nerve
Stimulator (TENS) Mode
Waveform
Asymmetrical Biphasic Square Pulse
Pulse Amplitude
Adjustable, 0 ~ 80mA at 500 ohm
Load each channel, 1mA/Step.
Pulse Width
Adjustable from 30-260
μ
s
Pulse Rate
Adjustable from 2 to 150 Hz, 1 Hz/step
Burst
Burst occurs twice every second, Pulse width(adjustable)
Frequency Fixed = 100 Hz
Modulation
The pulse width is automatically varied in a cyclic pattern over
an interval of nominally 10 seconds, (in max 150Hz) Pulse rate
decreases linearly over a period of 4 seconds from the control
setting value to a value which is 40% less. The lower pulse
rate will continue for 1 second. Then increase linearly over a 4
seconds period to its original value. The original pulse rate will
continue for 1 second. The cycle is then repeated.
Normal
Normal stimulation based on setting value. Only pulse width,
pulse rate and timer are adjustable in this mode.
