Calibrate the Temperature-sensing Modules
You can calibrate the 1756-IRT8I, 1756-IR12, and 1756-IT16 modules for use
with the following input types:
• RTD (Ohms) - 3- and 4-wire types (the 4-wire type is available only for the
1756-IRT8I module)
• Thermocouple (mV)
Note: You must inhibit the 1756-IR12 and 1756-IT16 modules before you
perform the calibration. Calibration via messaging is not allowed when the
modules are in Run mode (any time they have a connection open to the module).
