Accuracy:
Pressure at 20�C, Velocity (with Ellipsoidal Pitot Static Tube at 16�C, 1000 mbar):
Readings < 100 counts � 2 counts. Readings > 100 counts � 1% of reading � 1 count.
Velocity with dpm-i Pitot Tube at 16�C, 1000 mbar (PT factor set at 0.838):
� 3% of reading or � 0.05 m/sec (10 ft/min) � 1 count. Whichever is greater.
Velocity with dpm AneTM at 16�C, 1000 mbar (PT Factor set at 0.843):
Readings up to 8 m/sec (1575 ft/min) � 1% of reading � 0.03 m/sec.
Readings from 8 to 50 m/sec (1575 to 9842 ft/min) � 1 m/sec (197 ft/min)
