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 6000 ft/min (0.15 m/s through 30 m/s).
3
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.
4 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.
