What does a yellow label/tag signify on a device?

A yellow label or tag on a device typically signifies that there is a deviation from its normal operational parameters. This alert serves as a crucial indicator for personnel, suggesting that the device may not be functioning within its standard specifications and requires further inspection or action. It is essential for maintaining safety and quality assurance, as it notifies users that the device may pose a risk or may not perform adequately until issues are resolved.

In contrast, other options suggest statuses such as calibration or inactivity, which do not align with the common interpretations associated with a yellow label. This distinct marking is most often a warning regarding the current functionality and reliability of the device, rather than indicating successful calibration or operational status.
