1
Temperature compensated over an air temperature range of 40 to 150°F
(5 to 65°C).
2
The accuracy statement of ±3.0% of reading or ±3 ft/min (±0.015 m/s), whichever is
greater, begins at 30 ft/min through 9999 ft/min (0.15 m/s through 50 m/s).
3
Pressure velocity measurements are not recommended below 1000 ft/min (5 m/s) and
are best suited to velocities over 2000 ft/min (10.00 m/s). Range can vary depending
on barometric pressure.
4
Accuracy is a function of converting pressure to velocity. Conversion accuracy
improves when actual pressure values increase.
5
Accuracy with instrument case at 77°F (25°C), add uncertainty of 0.05°F/°F
(0.03°C/°C) for change in instrument temperature.
6
Accuracy with probe at 77°F (25°C). Add uncertainty of 0.1% RH/°F (0.2% RH/°C) for
change in probe temperature. Includes 1% hysteresis.
7
Overpressure range = 190 in. H
8
At 77°F (25°C). Add uncertainty of ±0.2%/°F (0.36%/°C) for change in temperature.
9
At calibration temperature. Add uncertainty of ±0.28%/°F (0.5%/°C) for change
in temperature.
