How many calibration points must be evaluated during the calibration of a remote reading thermometer?

• A. 2 Calibration Points
• B. 3 Calibration Points
• C. 4 Calibration Points
• D. 5 Calibration Points

Answer: (B)

For the calibration of a remote reading thermometer, evaluating three calibration points is essential because it ensures a comprehensive assessment across the expected operational range of the instrument. By utilizing three distinct points, calibration can establish the thermometer's accuracy at both lower and upper extremes as well as at a mid-range point. This approach enables technicians to identify non-linearities throughout the measurement range and confirm that the thermometer produces accurate readings under various temperature conditions. The three calibration points typically include a low point, a midpoint, and a high point, which effectively covers the thermometer's application range and helps to ensure reliable performance. This methodology aligns with standard calibration practices, which emphasize the importance of verifying instrument performance at multiple points to account for any discrepancies that may not be evident at just two points.
