25. The thermocouple table simply gives the voltage that results for a particular type of
thermocouple when the reference junctions are at a particular reference temperature,
and the measurement junction is at a temperature of interest.

26. In most cases, the measured voltage does not fall exactly on a table value. When this
happens, it is necessary to interpolate between table values that bracket the desired
value. In general the value of the temperature and voltage can be found using the
following interpolation equation:
