Cold junction compensation
If used, reference junction temperature is measured at
thermocouple termination using a precision thermistor, or
supplied by system, or by fixed configuration value.
Cold junction temperature error
±0.25 degree Celsius (local measurement). To reduce
temperature transients, thermocouple terminations should
not be installed in the same cabinet as high
heat-dissipation assemblies.
Conformity error
±0.3 degree Celsius, ±0.5 degree Fahrenheit.
Accuracy, at 25° C

on temperature measurement:
±0.2%
± 0.15%
Temperature sensitivity (0° to 60°C)
±0.004% of reading, ±1.5µV per °Celsius referred to input
Normal mode rejection
60dB, at 50/60 Hz, 100% span
Common mode rejection
120 dB at 50/60Hz, 100 ohm imbalance
Common mode voltage
3 V DC maximum
Maximum voltage between channels
50V
Normal mode voltage
5 V DC maximum
Update rate
60 Hz: approximately 60 milliseconds per channel
50 Hz: approximately 70 milliseconds per channel
