Which label indicates Calibration-refer to report, used when actual measurement values must be known to use the instrument?

• A. Red on white
• B. Black on white
• C. Black on yellow
• D. Black on red

Answer: (A)

Red ink on a white background signals Calibration—refer to report. This labeling is used to show that the instrument’s readings depend on calibration data stored in a certificate or calibration sheet. To use the instrument accurately, you must consult that calibration information to apply the correct corrections (offsets, gains, or temperature adjustments) so the measurements reflect true values. Without the calibration data, the instrument’s readings can be misleading. The other color schemes serve different purposes: they are typically used for general labeling, caution, or out-of-service indications and do not specifically instruct you to consult a calibration report for actual measurement values.
