Technical Specification - Verity Medical NeuroTrac MultiTENS Service Manual

TENS and STIM
1. Dual channel: individually isolated circuits.
2. Amplitude: 0-90 mA into 500 Ohm load ; indication only. Actual mA will tend to be
less than indicated due to electrode impedance: at 1000 Ohms load (Electrodes in poor
condition) the maximum will be limited to 70 mA, at 1500 Ohms load the maximum
will be limited to 65 mA.
3. Type: Constant Current, maximum output voltage 180 Volts +10 / -30 Volts.
4. Waveform: Asymmetrical, rectangular bi-phasic with zero DC current.
5. Selectable pulse width: 50 µS - 450 µS [10% accuracy].
6. Pulse Rate selection: in the continuous mode 2 – 200 Hz [5% accuracy].
7. Mode: Continuous, Burst or Modulated.
8. Burst mode: Bursts of 9 pulses [200 µS] at 150 Hz or 185 Hz, over 2 seconds.
9. Modulation mode: 6-second cycle of concurrent width modulation and pulse repetition
rate modulation.
10. Battery: PP3 Alkaline, 9V. Expected average battery life [of standard 800 mAh,
alkaline]: 24 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 6.2 (+/- 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.
Expected service life:
5 years. Careful use and maintenance extends the life of the unit over the service life limit.
Physical dimensions: 119.2 x 69 x 28.7 mm.
Weight: 104 g without battery
Environmental Conditions for use:
+5 to +40 degrees Centigrade. 15-90% Humidity. Atmospheric pressure: 700 hPa to 1 060 hPa.
Environmental conditions for storage & transport:
-25 to +70 degrees Centigrade. Up to 90% Humidity.
