What is calibration and why is it important?

Calibration is the fundamental process of observing instrument performance so that, if necessary, adjustments can be made to the instrument in order to achieve accurate measurements. Calibrations help to deliver reliable results and maintain measurement integrity in a company’s quality system. Calibrated devices are crucial when it comes to enhancing the quality of products, and accredited calibration certificates document that companies comply with regulatory standards.

 

During calibration, measurement values are compared against known standards to determine any deviations or inaccuracies. This meticulous procedure involves adjustments to align the instrument's readings with the reference standards, such as test weights. Proper calibration requires precision, expertise, and adherence to recognized procedures.

What is the difference between calibration and routine testing?

When a balance or scale is no longer measuring correctly within the allowed range for its intended use, a calibration is required. To fix this, a trained technician would perform a calibration using special test weights that are certified and accurately calibrated.

In addition to periodic calibrations, routine or functional tests are carried out to ensure that the weighing equipment is performing to expectations. The frequency of these tests depends on how risky the weighing process is. Typically, the person operating the equipment conducts routine tests using calibrated and certified test weights.

What are the top reasons for calibrating measurement equipment?

Regular calibration of measurement equipment is essential for several reasons:

  1. Maintain accuracy and remain compliant. Many industries have regulatory standards in place for measurement accuracy. Regular calibration verifies that your equipment meets these standards, preventing potential fines and safeguarding measurement results. Consistency among different measuring tools also enables high-quality production.

  2. Minimize costly errors and avoid fines. Inaccurate measurements can result in costly errors. Underweight production can lead to fines and dissatisfied customers, while overproduction wastes resources and reduces profits. Calibration helps minimize errors by optimizing instrument precision so that your measurements are within the required specifications.

  3. Eliminate safety risks. Equipment that is out of calibration can pose serious safety risks, including spoilage and the spread of foodborne illnesses. In hazardous work areas, uncalibrated equipment may expose employees to electrical hazards or other injuries. Regular calibration protects the safety and integrity of your operations.

What is measurement uncertainty?

Weighing uncertainty, also known as measurement uncertainty in weighing, refers to the range of values that can reasonably be assumed to encompass the exact weight of a measured object. In simpler terms, it represents the potential variation or margin of error in weighing measurements.

By understanding and considering weighing uncertainty, you gain insights into the potential variability in your weighing results. This knowledge helps you make informed decisions and determine the reliability and accuracy of your measurements. It also aids in setting appropriate tolerance limits and ensuring compliance with regulatory standards. Embracing weighing uncertainty empowers you to have a more comprehensive understanding of the reliability and limitations of your weighing process.

What is performance verification of measurement devices?

Performance verification is essential to confirm that equipment operates according to agreed specifications, maintains productivity, and complies with standards. Regular performance verifications by our expert technicians helps monitor data quality, equipment reliability, and product safety.

Documented proof of steady process performance is crucial in maintaining consistent process quality. By effectively managing process risks, you can help prevent problems and rest assured that audits are successful.

How to find a reliable service provider?

First and foremost, choosing a trustworthy provider can make all the difference to protect measurement accuracy and give you peace of mind. Keep an eye out for certifications like ISO17025, which guarantees adherence to widely accepted quality standards.

A dependable calibration service provider will provide thorough documentation, including calibration certificates and reports, to confirm that your measurements can be traced, and you're prepared for any audits. With a global network of accredited technicians and calibration standards that can be easily traced, METTLER TOLEDO is equipped to handle all your service needs.
