5.2.1.6 RTD Polynomial Conversion
EDIT SPRT 01
PROBE SER#: 1
CONVERSION: POLYNOMIAL
A[0]: -35.540960

The user-defined parameters for the polynomial conversion are A[0] ( a
0
)
through A[10] ( a
10
). Any unused coefficients should be set to 0.
5.2.1.7 Thermistor T(R) Conversion
EDIT STHR 01
PROBE SER#: 1
CONVERSION: THRM-T(R)
A[0]: -35.540960
A[1]: 0.36568108
A[2]: -1.884784E-4
A[3]: 7.26691E-6
The following Steinhart-Hart equation is used for the thermistor T(R)
conversion:
T r K A A r A r A r ( )[ ] [ ln ]
= + + +

The user-defined parameters for the thermistor T(R) conversion are A[0] ( A
0
)
through A[3] ( A
3
). If A
2
is not used, as is the case with some calibrations, A[2]
should be set to 0.0.
