Accuracy
after 2 minutes warmup:
For values between 0 and 40 mmHg: ±2.0 mmHg (±0.29 kPa)
For values from 41 to 70 mmHg: ±5 % of reading
For values from 71 to 100 mmHg: ±8 % of reading
For values from 101 to 150 mmHg: ±10 % of reading
At respiration rates above 80 rpm, all ranges are ±12 % of actual. The
