  • Page 28: Part 5 - Calibration

    Part 5 – Calibration Overview and Methods The instrument must be calibrated periodically to maintain a high degree of measurement accuracy. Frequency of calibration must be determined by the application. High temperature applications or applications involving other extreme operating conditions may require more frequent calibration than those that operate at more ambient level temperatures.
