Does anyone know if a new VP2 anemometer and wind vane have a known break-in period before they loosen up? I just mounted one next to my two other weather stations, and it seems to be reading 1-2 MPH lower than the others in sub-8 MPH winds. I can see from the ground that the cups are a bit hesitant to start spinning compared with the other two stations, and the vane likewise hesitates to change direction in variable winds. Just wondering if this is normal for a brand new sensor, if I should take it apart and do some maintenance, or if being exposed to tropical storm force winds clamped to my car for an hour will help it rotate more freely.....
