Vantage Pro 2 Data Logger

When WD downloads data from the vp2 data logger I have been getting large spikes in windspeed and temperature. Any ideas on whats causing this and how I can fix it?

Hi
what archive intervzal do you have the data logger set to?
make sure you set wd to pad out the data at the same interval (in the data logger setup)
using 1 minute interval works best, as that is the interval wd stores its data
