C-18 Calibration
Checking Indication
Accuracy
• After calibrating input, make sure to check indication accuracy to make
sure that the Bulletin 900 Controller has been correctly calibrated.
• Operate the Bulletin 900 Controller in the PV/SP monitor mode.
• Check the indication accuracy at the Upper- and Lower-Limits and
mid-point.
Checking Accuracy of a Thermocouple or Non-Contact
Temperature Sensor
• Preparation: The following figure shows the required device
connection. Make sure that the Bulletin 900 Controller and cold
junction compensator are connected by a compensating conductor for
the thermocouple that is to be used during actual operation. For the
non-contact temperature sensor, connect a K thermocouple, and
configured the Input Type to the K thermocouple.
