12
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. Pulse width: 220
µ
S [2% accuracy].
6. Pulse Rate: 90Hz (Continuous mode) [2% accuracy].
7. Mode: Continuous (Boost mode).
8. Burst mode: Bursts of 9 pulses [200
µ
S] at 150 Hz, repeating twice
every second (Rest mode).
9. Ramp up Time: 0.8 seconds from Rest to Boost
10. Time duration: continuous until switched off.
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: 0.09KG without battery, 0.14KG with battery.
16. Environmental conditions for storage & transport:
-10 to +50 degrees Centigrade
0-90% Humidity.
