1) Percentage of selected range.

2) Uncertainty limited by system noise for ranges of 0.5 inH2O and below.

3) Includes errors of offset, span, hysteresis and thermal effects.

4) Each selected range has the specified resolution

5) ENOB stated for fBW set to 1.0 Hz.

6) The internal update rate is fixed and does not change with range or filter settings. Sampling at lower data rates are possible provided the

Nyquist frequency is observed. It is suggested to sample at least 3x the set fBW frequency.

7) Total error band within 24 hours of a sensor auto-zero. Includes all error components of TEB.

8) YR1 is the first year. The most significant drift occurs during the first year and is lessened for each subsequent year. For each subsequent

year, use 25% of the prior years' drift figure to estimate the drift for that specific year.
