formula
Converted to a resistance value at
the reference temperature using
the formula below and result dis-
played.
Rtref : Resistance after compen-
sation for reference tem-
perature of tref°C
Rt : Resistance measured at
the temperature of t°C
tref : Reference temperature [°C]
t : Actual temperature used
for measurement [°C]
