kind of nonvolatile memory, such as EEPROM. In operation, every time the
system makes a measurement, it also reads the temperature and looks up the
actual input value that corresponds to that measurement value at that tempera-
ture. If there are a lot of data points, the table will get very large, so you may want
to calculate the compensation value instead of using a table. To make use of this
technique, you must be able to do the following:
.
Ensure that all the high-precision parts of the circuit and the temperature
sensor can be collected into one area and are at the same temperature. This
may require potting the parts or using a fan. The non-high ...
