What color is the label used to indicate a device requires no calibration?

The label indicating that a device requires no calibration is typically colored orange. This color is used to signify that the device is either self-calibrating or is in a state where calibration is not necessary for accurate functioning. This helps ensure that personnel working with these devices can quickly and easily identify them as ready for use without the need for further adjustment, which contributes to efficient workflow in environments where multiple instruments may require varying levels of maintenance and oversight.

The use of orange provides a clear visual cue that is easily recognized among various labeling colors commonly used for different purposes in a laboratory or quality assurance setting, enhancing safety and operational efficiency.
