I have an issue about wind vane's direction degree on NRG Symphonie data logger screen. I want to ask some question;
1) I have 2 channel for wind vane 7 & 8 for wind vane 7 is always show 179 or 359 1st is for average ?
2) we use wind vane for showing people what is wane and anemometer in the office . So it is not professional system and we do not record our data .
However at the 8 channel when i directed wind vane to 0 degree ( i did all offset and scale ) it shows 45degree and then when i directed to other direction it shows 45 or 0 it walks always same degrees . Why is it occur ? I think i missed some steps ?
