Conversions for each of the thermocouple types accept optional calibration
data. This can be used to improve the measurement accuracy. CAL PTS indi-
cates the number of calibration points used, up to three. T
n is the temperature
of the point. ADJ n is the temperature deviation from the reference function at
the point. The temperature measurement will be adjusted by this amount when
measuring at this temperature. A polynomial interpolation function is used for
measurements between calibration points. If calibration data is not available or
is not to be used, the ADJ
n parameters should all be set to 0.0. This will cause
the temperature to be calculated according to the standard reference functions.
Some thermocouple conversions (types R, S, and gold-platinum) also accept
polynomial calibration coefficients. This produces a temperature-dependent ad-
justment to the voltage according to the polynomial function:

The probe parameters DC1 and DC2 are used to set the values of

and

respectively. If no calibration coefficients are available or if only the standard
reference function is to be used, DC1 and DC2 should be set to 0.0. If these co-
efficients are used, the ADJn parameters described above must be set to 0.

The thermocouple table conversion allows calculation of temperature by inter-
polating from a table. You can enter the temperatures (in °C) and voltages (in
V) from a reference or calibration table for one to ten points. The number of
points is specified by TABLE PTS. To calculate temperature, a polynomial in-
terpolation is done using up to four of the points in the table closest to the given
temperature or voltage. The zero point (0 V at 0°C) is automatically included in
the table whether it is explicitly specified or not.
