The usable ranges of the
thermocouple types are
shown in The table above.
If having a high accuracy
over a specific operating
range is desirable then the
input should be calibrated
over that range. Follow the
calibration procedure for
normal calibration with the
following changes. Use the
low end of the desired range
as the zero value and the
high end as the span value.
There will be more
interaction between zero
and span with this method.
The desired operating
range must fit with the
limits of the table.
