<br />Directional sensitivity of the Model 8475 is +5%/-20% of reading +0/-0.05 m/s (+0/-10 ft/min) over 270' solid angle regardless of flow direction.
<br />3 Standard deviation, based on one minute average from 0.5 to 5.0 m/s (100 to 1000 ft/min).
<br />4 For 63% of final value, tested at 7.5 m/s (1500 ft/min).
<br />5 For 63% of final value, tested at 2.5 m/s (500 ft/min).
<br />6 Input voltage must be maintained within specifications at the transducer.
<br />7 Calibration occurs with sensor oriented horizontally in a horizontal flow. Uncertainty increases in downward vertical flow at velocities less than 50 ft/min (0.25 m/s).
<br />All specifications subject to change without notice.
