Thermocouple
The following table provides the total error expected of the
thermocouple based on the thermocouple type, and the given
reference point, at 25°C. The calculations assumed typical
hardware/software error and typical CJC accuracy at 25°C.
The following table provides the total error expected over the
temperature range of the module (0 to 60°C) for each thermocouple
based upon the type, and the given reference point, at the extremes of
the temperature range (0 or 60°C). The calculations are based on
maximum hardware/software error and maximum CJC inaccuracy
over temperature.
