Wind Speed Functions
Modes: Moving 3-second average ( ), maximum 3-second gust since power
on (MAX) and average since power on (AVG).
Units: Knots (KT), meters per second (M/S), kilometers per hour (KM/H), miles per
hour (MPH), feet per minute (FPM) and Beaufort force (“.F”).
On-Axis Accuracy: greater of ± 3% of reading or ± least significant digit.
Off-Axis Response: -1% @ 5°, -2% @ 10°, -3% @ 15°.
Accuracy Degradation: (loss of accuracy due to impeller bearing wear) < 2%
after 100 hours use at 7 M/S [14 KT, 25 KM/H, 16 MPH, 1400 FPM].
Minimum Speed: 0.3 M/S [0.6 KT, 1.0 KM/H, 0.7 MPH, 59.0 FPM].
Maximum Speed: 40 M/S [78 KT, 144 KM/H, 89 MPH]; 1,990 FPM (display limit).
Display
Type: Reflective 2 ½ digit LCD.
Digit Height: 10 mm (0.4 in.).
Update: 1 second.
Range and Resolution: Depends on measurement scale selected – see chart:
Display Temperature Limitations: Normal operation from -15°C to 60°C [-4°F
to 140°F]. Below -15°C [-4°F], accurate readings may be taken by keeping the
unit warmer than -15°C [4°F] and exposing it for the minimum time necessary
to take a reading (less than one minute).
Automatic Shutdown: After 30 minutes of no button presses.
Environmental
Sealing: Electronics enclosure IP67 – water resistant to 1 m. [3 ft.]. Floats.
Shock: Drop tested to 2 m. [6 ft.].
Storage Temperature: Prolonged exposure to temperatures below -20°C [-4°F]
or above 80°C [176°F] may cause permanent damage.
Physical
Buttons: Two sealed tactile rubber buttons control all functions.
Battery: User-replaceable CR2032 coin cell. Typical life, 400 hrs.
Impeller: 25 mm [1 in] diameter, sapphire bearings, light weight. User-replaceable
impeller/housing assembly.
Case: Slip-on case prevents damage to display and moving parts.
Dimensions: 122 x 42 x 14 mm. [4.8 x 1.7 x 0.6 in]; case, 117 x 46 x 19 mm. [4.6 x
1.8 x 0.7 in.]; lanyard, 0.5 m. [10 in.].
