1. the process of checking, adjusting, or determining the accuracy of a measuring instrument by comparison with a standard
2. careful assessments or adjustments made to achieve accuracy or desired results

Examples

• The laboratory equipment requires regular calibrations to ensure accurate measurements.
• The technician performed calibrations on all the digital scales before the experiment.
• Proper calibrations of the telescope allowed astronomers to make precise observations.
• The company’s quality control department handles all instrument calibrations.
• Without proper calibrations, the test results would be unreliable.
• The engineer made several calibrations to optimize the machine’s performance.
• Annual calibrations are mandatory for all medical devices in the hospital.
