Specifications
TENS and STIM
1. Dual channel: individually isolated circuits.
2. Amplitude: 0 mA - 90 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 µS - 450 µS [2% accuracy].
6. Pulse Rate selection: in the continuous mode 2 Hz – 200 Hz [2% accuracy].
7. Mode: Continuous, Burst or Modulated.
8. Burst mode: Bursts of 9 pulses [200 µS] at 150 Hz or 185 Hz, repeating twice every second.
9.Modulation mode: 6-second cycle of concurrent width
modulation and pulse repetition rate modulation.
TENS 7: Width starting at 50 µS and increasing exponentially to 250 µS
in three seconds and then returning back to 50 µS in the next three
seconds. Rate starting 20 Hz, increasing exponentially to 85 Hz and
then returning to 100 Hz.
TENS 8: Width fixed at 200 µS. Rate starting 32 Hz, increasing
exponentially to 100 Hz over 3 seconds and then returning to 32 Hz in
the next 3 seconds.
10. Time duration of the treatment selectable: 1 minute to 12 hours (TENS), 1 minute to 90 minutes (STIM).
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.
