* The Factory Calibrated millivolt values for the Thermocouple Differential Input are for a pair
of J thermocouples at an ambient temperature mean of 450°F / 232°C. Other thermocouple
types and ambient temperature means may be accomplished via Field Calibration of the input,
with the range value limits being –4 mV to +16 mV for the zero and span values.
** The range values for Radiamatic Type RI are customer configurable within the limits shown.
