Performance Accuracy


  • Measuring range: 0%~100%; Resolution 1%
  • Accuracy: 70%~100%±2%; less than 70% unspecified
  • Low perfusion test (0.5% modulation)
    (This test uses an SpO2 Simulator to provide a simulated pulse rate, with adjustable amplitude settings of various SpO2 levels. The module must maintain accuracy in accordance with ISO 80601-2-61 for pulse rate and SpO2 at the lowest obtainable pulse.)

Pulse rate

  • Range: 30~250bpm with resolution 1bpm
  • Accuracy ±1bpm or ±1%, whichever is greater


  • Advanced anti-motion algorithm reduces the interrupted effects of a movement to the minimum. Any motion within 2 Hz and under 30 seconds will not affect performance
