The purpose of a calibration check is to ensure:

The purpose of a calibration check is fundamentally to verify that the instrument operates within its specified range and accuracy requirements. This process involves comparing the instrument's readings against known standards or reference points to confirm that it is measuring correctly and can be relied upon for accurate data collection. Ensuring the instrument is within specifications is crucial for maintaining the integrity of measurements, as deviations can lead to incorrect data that may impact processes or systems controlled by the instrument. Calibration checks are a necessary part of quality control in various applications, emphasizing the importance of accuracy and reliability in instrumentation.
