Since changing batteries last week I had noted suspiciously low wind readings given conditions at the time. It was confirmed this weekend as we have had constant gale force winds with other instruments in the area reading almost double what I was seeing. I also noted a friend’s station looking similar to mine. This morning I tried out of frustration setting the unit to power save mode and it began reading normally instantly…changing back to normal caused readings to be fine for a minute or so, then go back to problem state. Our two plots below
Here is my plot when going back and forth between normal and power save mode.
Here is my friend’s when he toggled to power save this morning. These are both now correct given current conditions here.
