APPENDIX 4
CALIBRATION
•
To maintain optimum performance, once a year calibrate the analog input, the
cold junction and milliamp output (when used). To achieve published accuracy
specifications, follow directions carefully and use calibrated instruments of like
quality to those suggested.
•
If the controller is moved into an alternate case, or the hardware configuration is
changed, and the thermocouple input is needed, recalibrate the cold junction
for maximum accuracy. Failure to do so may result in small junction tempera-
ture (0.6°C/1.1°F).
Access the parts of the calibration menu as shown in
Figure A4.2.
