What does the thermocouple calibration method involve?

• A. Using random temperature points for testing
• B. Comparing with a digital thermometer only
• C. Using known temperature references for accuracy
• D. Adjusting the thermocouple manually

Answer: (C)

The thermocouple calibration method primarily involves using known temperature references for accuracy. This approach ensures that the thermocouple's output is compared against established temperature standards, which are well-defined and reproducible. By applying these known reference points, technicians can determine the thermocouple's accuracy and make adjustments if necessary. This method is crucial because it relies on established benchmarks to validate the measurements taken by the thermocouple, ensuring they meet required specifications and standards. Utilizing known temperature references allows for systematic calibration, which is more reliable than random temperature points, as it helps identify specific deviations across the measurement range. In contrast to comparing with a digital thermometer alone or adjusting the thermocouple manually, the reference method provides a comprehensive understanding of the thermocouple's performance under controlled conditions, leading to more precise and reliable results in temperature measurements.
