Measurement Definition
|
Cup revolutions are accumulated every three seconds for the
duration of the logging interval
Wind speed: Average speed for the entire logging interval
Gust speed: The highest three-second wind recorded during the logging interval
|
Unit vector averaging used; vector components for each wind measurement are calculated every three seconds for duration of logging interval

Battery Type/ Power Source
|
Two AA 1.2V rechargeable NiMH batteries, powered by built-in solar panel or two AA 1.5 V lithium batteries for operating conditions of -40 to 70°C (-40 to 158°F)

Battery Life
|
With NiMH batteries: Typical 3–5 years when operated in the temperature range -20° to 40°C (-4°F to 104°F) and positioned toward the sun (see Deployment and Mounting), operation outside this range will reduce the battery service life With lithium batteries: 1 year, typical use
