Multi-Functional Device The Verity NeuroTrac Rehab Device offers many different functionalities, ranging from 10 pre-set programs and 10 pre-set neuromuscular stimulating programs. It also is a remote switch control devices that facilitates a range of rehabilitation protocols, including Foot Drop, which offers comfort and care at your finger tips. Technical Specifications: Dual channel: individually isolated circuits. 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. Type: Constant Current, maximum output voltage 180 Volts +10 / -30 Volts. Waveform: Asymmetrical, rectangular bi-phasic with zero DC current. Selectable pulse width: 50 �S � 450 ?S [2% accuracy]. Pulse Rate selection: in the continuous mode 2 � 200 Hz [2% accuracy]. Mode: Continuous, Burst or Modulated. Burst mode: Bursts of 9 pulses [200 ?S] at 150 Hz or 185 Hz, over 2 seconds. Modulation mode: 6-second cycle of concurrent width modulation and pulse repetition rate modulation. TENS 7: Width starting at 50 �S and increasing exponentially to 250?S in three seconds and then returning back to 50 �S 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 ?S. Rate starting 32 Hz, increasing exponentially to 100 Hz over 3 seconds and then returning to 32 Hz in the next 3 seconds. Time duration of the custom programmes selectable: 1 minute to 12 hours. Low Battery Indicator: If the battery goes below 6.9 volts +/- 0.2 volts the battery symbol will flash on/off once every second. If the battery voltage is below 6.6 (+/- 0.2) volts the unit will not turn on. 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.
