APPENDIX E: TRACEABILITY OF INSTRUMENT CALIBRATION
The temperature sources (blackbodies) used to calibrate this instrument are traceable
to the U.S. National Institute of Standards and Technology (NIST).
The calibration sources for this instrument were certified by a NIST certified calibra-
tion laboratory and are traceable to NIST primary standards. The certificate describes
the equipment used for calibration and any corresponding NIST report numbers. In
addition, the certificate lists test accuracy data and the next calibration date.
NIST certificates are available as an option (must be ordered with the instrument).
Contact the manufacturer (not NIST) to order this option.
