General Conditions – From 15 to 35 degrees C. ambient at the interface board, source resistance less than

1k Ohms. Includes linearity, drift, offset, resolution, and calibration error. 16 bit (0.0015%) resolution in

use.

Thermocouple Conditions – Same as General Conditions. Does not include the accuracy of the

thermocouple itself (cold junction error must be added in; cold junction compensation with T21 terminal

panel only; please see your terminal panel manual’s specifications for cold junction compensation error).

Resolution assumes 16 bit resolution in use; it is approximate because resolution varies with temperature.

Thermocouples use the 50 mV range. For inputs below -5 mV (below approximately -100 degrees C.) use

the +/-25 mV range. For the best resolution use the 50 mV range above -5 mV.
