How fragile is the anemometer?
AA common mistake is to over estimate the durability of the anemometer. The anemometer is fragile and should be treated with the appropriate care. As you install the anemometer with the nuts and screws, make sure that the anemometer is securly attached, but be careful as you tighten the nuts and screws that you don’t break or crack the anemometer. You should also be careful to not over-torque the nuts.
