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.
Installation Complete. (For OEM installations preset the same adjustments. Indi­vidual calibration is not required.)
