Specifications
TENS
1. Dual channel: individually isolated circuits.
2. Amplitude: 0 mA - 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 µS - 300 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, repeating twice every second.
9. Modulation mode: 6-second cycle of concurrent width modulation and pulse repetition rate modulation. Width starting at 200 µS and decreasing exponentially to 100 µS in three seconds and then returning back to 200 µS in the next three seconds. Rate starting at 100 Hz, decreasing exponentially to 65 Hz and then returning to 100 Hz.
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. |
