Calibration As the calibration procedure requires a calibr ation source that can output stab le µv signals, calibration of the four channels is normally done in the factory prior to shipping. Calibrating 4 Channels for K Type Thermocouple If user calibration is required, the f ollowing procedure should be f ollowed. It is assumed that the user has a thermocouple calibration source available. When the controller is switched on, allow a few minutes warmup to let the reference junction stabilize to the connector ter minal block temperature. Setup Smart Register (SMT) See Page 4 and carry out Steps to 7 to select the required line frequency and thermocouple type. 2 Connect to the Calibrated Source Connect a standard K type ther mocouple plug to the calibration source. 3 Connect to the Input Module Connect the standard K type ther mocouple cable to the rele vant pins on the input module of the thermocouple input to be calibrated.
