HFE/MET/M1 - Induced voltage on wind speed sensor cable
DataStreams:hfemetM1.b1
Description:
The cable for the wind monitor is not a twisted pair shielded cable.  This caused an 
induced voltage on the wind sensor wires from the wind direction measurement excitation 
voltage.  A small offset is added into the wind speeds.  This value varies.  Most frequently 
the values of 0.49, 0.588 and 0.686 m/s were added into the wind speed.  On 11/27/2008 the 
value jumped to 0.98 m/s for most of the day.
Suggestions: 
null
Measurements:hfemetM1.b1:
  • Wind speed arithmetic mean(wspd_arith_mean)
  • Wind speed vector mean(wspd_vec_mean)
