Calibration

cRIO01 500m, y[V]がADの電圧値。上からAD00,01,02,03 

t[℃]=(y[V]/10/(1+3300/430)/1.e-3-107.79)/.388+20.0
h[%]=-y[V]/5*100/2
p[hPa]=-y[V]/2/5*(1100-800)+800
vac[Pa]=10^[2*y[V]-13.0]

cRIO02 2000m 

t[℃]=(y[V]/10/(1+3300/430)/1.e-3-107.79)/.388+20.0
h[%]=y[V]/5*100/2
p[hPa]=y[V]/2/5*(1100-800)+800
vac[Pa]=10^[2*y[V]-13.0]
