Note
•
Tidal Volume Accuracy ± 3 % of reading or ±5 ml, whichever is
greater
•

•
Below 0.25 lpm, measurement accuracy is obtained by allowing the
Analyzer to fully warm up, and manually zeroing before reading or
documenting a measurement.
Breath Parameter Accuracy Specifications
Breath parameter accuracy specifications are listed in Table 1-7.
Note
If a choice of readings is indicated by an “or”, choose whichever is
greater; for example, 3 % or 250 ml.
