TENS
1.
Dual channel: individually isolated circuits.
2.
Amplitude: 0-80 mA; indication only; actual mA will tend to be less
than indicated due to electrode impedance.
3.
Type: Constant Current.
4.
Waveform: Asymmetrical, rectangular bi-phasic with zero DC
current.
5.
Selectable pulse width: 50
µ
S -300
µ
S [2% accuracy].
6.
Pulse Rate selection: in the continuous mode 2 – 200 Hz
[2% accuracy].
7.
Mode: Continuous, Burst or Modulated.
8.
Burst mode: Bursts of 9 pulses [200
µ
S] at 150 Hz, repeating twice
every second.
9.
Modulation mode: 6-second cycle of concurrent width
modulation and pulse repetition rate modulation. Width starting at
200
µ
S and decreasing exponentially to 100
µ
S in three seconds and
then returning back to 200
µ
S in the next three seconds. Rate starting
at 100Hz, decreasing exponentially to 65 Hz and then returning to
100Hz.
10.
Time duration of the treatment selectable: 1 minute to 12 hours.
11.
Low Battery Indicator: If the battery goes below 6.9 volts +/- 0.2
volts the battery symbol will flash on/off once every second.
12.
If the battery voltage is below 6.6 (+/- 0.2) volts the unit will not turn
on.
13.
Open Electrode Detect: If an open circuit is detected at the
output of channel A or B the output current will be reset at zero.
14.
Physical dimensions: 108 x 62 x 23 mm.
15.
Weight: 0.07KG without battery, 0.1KG with battery.
16.
Environmental conditions for storage & transport:
-10 to +50 degrees Centigrade
0-90% Humidity.
