NOTES:
(1) Thermocouple characteristics per NIST monograph 175, ITS-90.
(2) Output Range and Supply Current specifications are based on minimum output load resistance.
Minimum output load resistance is calculated by V
OUT
2 /P
E
, where P
E
is the output Effective Available
Power that guarantees output range, accuracy, and linearity specifications.
(3) Accuracy includes the effects of repeatability, hysteresis, and conformity.
(4) V
Z
is the nominal input voltage that results in a 0V output.
(5)The CJC sensor accuracy should be added to the module accuracy and thermocouple accuracy to
compute overall measurement accuracy.
