Accuracy 0 to 70: ± 1 Resp/min
71 to 120: ± 2 Resp/min
121 to 150: ± 3 Resp/min
Flow rate 50 ml/min, (42.5 < flow < 65) flow measured by volume
Waveform sampling 20 samples/s
Initialization Time 40 s (typical)
System Response Time 5.6 s (typical combined response time)
Calibration Interval Initially calibrate after 1,200 operating hours, then once a year or
after 4,000 operating hours, whichever comes first. The initial
calibration should not occur before 720 hours of use. If the initial
calibration is done before 720 hours of use, the module will reset
to require its next calibration after 1200 hours, instead of after
4000 hours.
