Averaging for a Thermocouple Range
When the input range is set to a thermocouple (K, J or T type), processing like that
shown below is carried out internally in the analog I/O unit.

Starting from the most recent data, the data from the last five times is taken. The
maximum and minimum values are deleted, and then averaging is carried out on the
remaining three items. The value obtained from the most recent averaging is normally
used as the value output at this time. (If a fraction results from the calculation, it is
rounded off.)
