Why instruments lose their calibration

Events Require Additional Calibration: Keeping a regular calibration schedule is a critical part of many quality processes, but sometimes necessity compels you to get an additional calibration outside of your normal scope. Unless your measuring instrument is specifically designed for excess moisture, dusty environments, or extream temperature fluctuations, a major environmental change could cause your equipment to loose accuracy. Most measuring equipment is more delicate than it seems.

Small drop or bump can skew its results. Certain Quality or Process Requirments may require additional calibrations. You can check with your quality manager for these requirements. Sometimes its better safe than sorry. Company Name.

Causes of Calibration Drift Drift errors are caused by deviations in the performance of the measuring instrument that occurs after calibration. The specific causes may vary depending on the types of gauge you are using; some of the most common causes of gauge drift include: Environment Changes — A significantly sudden change in temperature or humidity can cause drift.

Sudden Shock — Sudden mechanical or electrical shock or vibration will affect the instrument. Dropping the instrument can equal sudden shock, and calibration errors will follow. Frequency — Frequent use will speed up the need for calibration. Natural Degradation — Calibration over time with use eventually causes drift. Why Is Calibration Drift Important? Solving Calibration Drift Though you can take precautions to prevent some environmental causes of gauge drift, the best way to protect your equipment is to have your instruments professionally calibrated on a regular basis.

Calibration Solutions Calibration drift as shown above, can take the instruments out of the field and slow down your operation. This site uses Akismet to reduce spam.
