sensor's triple points of water, and R(0.01) is named as Rtp
in AM8010. The details can be found in ITS-90 standard.
The sensor's parameters a, b and c can be calculated based
on the above data and formula.
5. Key in the a, b, c and Rtp into AM8010. After the
parameters are saved, the system calibration is done.
More details about the coefficients and temperature
calculations can be found in ITS-90 standard.
Turn off the power after calibration.
