Suitable for Obstetrics and Labour pain relief Digital Dual Channel Obstetrics TENS unit 1 Dedicated Labour Pain programme for ease of use Remote Boost switch for additional pain control at times of intense pain No known side effects for mother or baby For use during labour User friendly Compact, light and reliable
Dual channel: individually isolated circuits. Amplitude: 0-80 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. Pulse width: 220µS [2% accuracy]. Pulse Rate: 90Hz (Continuous mode) [2% accuracy]. Mode: Continuous (Boost mode). Burst mode: Bursts of 9 pulses [200 µS] at 150 Hz, repeating twice every second (Rest mode). Ramp up Time: 0.8 seconds from Rest to Boost. Time duration: continuous until switched off. 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.
