INSTALLATION INSTRUCTIONS
The following procedure is recommended:
1. Install the SmartIRt/c as close as practical to view the target material to be
measured.
2. Wire the SmartIRt/c to the controller, PLC, etc. in standard fashion (see PIN-
OUT and wiring diagram)
3. Bring the process up to normal operating temperature and measure the actual
temperature of the target material with the Microscanner D-Series, DX-Series
Infrared Thermometer or any other reliable reference.
4. Adjust "input offset," "zero," "low cal," on the readout device to match the
reading of your reference.
