Specifications
15
Power Requirements:
Four AA-size batteries (included) or AC adapter (optional) 7.2 VDC,
300 mA, 4-18 watts (input voltage and frequency vary depending on which
adapter is used)
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. 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
2
O (7 psi , 360 mmHg, 48 kPa).
