Calibrate the Module for a Thermocouple Input Type
Follow these steps to calibrate your module.
1. Connect your voltage calibrator to all module channels being calibrated.
2. Go online with your project.
3. Right-click the module you want to calibrate and choose Properties.
4. On the Configuration tab, make sure the Input Type for each channel to
be calibrated is set to Thermocouple (mV).
The sensor type selection does not impact calibration.
5. Make sure that the controller is in Program Mode or the Connection is
Inhibited (available via the Connection tab).
The 1756-IRT8I module can only be calibrated when the Connection is
Inhibited.
IMPORTANT
The 1756-IRT8I module channels configured for Thermocouple inputs perform
a wire resistance self-calibration when the module power is cycled.
