EMG (Biofeedback)

• Dual channel EMG
• EMG Range: 0.2 to 2000 μV RMS (continuous)
• Sensitivity: 0.l μV RMS
• Accuracy: 4% of μV reading +/-0.3 μV at 200 Hz
• Selectable Bandpass filter - 3db Bandwidth,
  • a. Wide: 18 Hz +/- 4 Hz to 370 Hz +/- 10% - Reading below 235 microvolts 10 Hz +/-3 Hz to 370 Hz +/- 10% - Reading above 235 microvolts
  • b. Narrow: 100 Hz +/- 5% to 370 Hz +/- 10%
• Notch filter: 50 Hz (Canada 60Hz) - 33 dbs (0. 1% accuracy)
• Common Mode Rejection Ratio: 130 dbs Minimum @ 50 Hz
• Batteries: 4 x 1.5V ( AA battery)
• Optional Charger: CE approved.
• Work / Rest periods: 2-99 seconds
• Number of Trials: 1-99

STIM (Neuromuscular Stimulation)

• Four channel Stimulator
• Amplitude: 0-90 mA into 500 Ohm load - 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 75 mA, at 1500 Ohms
  load the maximum will be limited to 50 mA.
• Type: Constant current, maximum output
  voltage 70 Volts +5 / -10 Volts
• Waveform: Symmetrical, rectangular,
  bi-phasic with net zero DC current
• Pulse width selection: 50-450 μS (2% accuracy)
• Pulse rate selection: 2-100 Hz (2% accuracy)
• Work / Rest periods: 2-99 seconds
• Time 1 - 99 minutes
• Ramp up time: 0.1 - 9.9 seconds
• Preset and user programmable treatment Programs
• Automatic output shut off with detection of open electrode above 0.5 mA
   

 
Battery: Low battery indication at 5.4 volts +/- 0.2 volts, automatic shut off when voltage dropps below the low indication. Replace the batteries immediately! The device goes off automatically when not in use (energy saving): for example when in settings and no key pressed over 1 minute, when in stimulation mode (home screen) and all channels are 0mA.

Expected average battery set life [of standard 800 mAh, alkaline]:
8-16 hours in  STIM, 25 hours in EMG mode.

Environmental Conditions for use: +10 to +30 degrees Centigrade. 0-90% Humidity.

Environmental conditions for storage & transport: -10 to +50 degrees Centigrade. 0-90% Humidity.

Physical dimensions: Length 150 mm, Width 89 mm, Depth 35 mm.

Weight: MyoPlus4 Pro device: 0.16 Kg (without batteries).
