Thermocouple Temperature Accuracy
Accuracy specifications apply using a slow sample rate. When using a medium or fast sample rate (NPLC < 10), increase
the accuracy specification by 25 %. If the environment temperature is outside the specified range, increase the accuracy
specification by 12 % for every 1 °C outside the specified environment temperature range. Accuracy with fixed/external
CJC does not include the accuracy of the reference junction temperature. Linear interpolation may be used between
points in the table. Specifications do not include sensor accuracy. The practical range of temperature measurement
depends on the sensor.
