White Paper- Calibrating Weighing Instruments - Part 1

Product catalog summary

Introduction
This document discusses the calibration of weighing instruments, emphasizing the importance of accurate weighing results for legal and quality systems. The responsibility for ensuring measurement capability lies with the instrument's owner or user.

Calibration and Legal Verification
Calibration and verification serve different purposes. Calibration measures deviation from a standard, while verification checks permissible errors. Both processes confirm measurement capability, but legal verification is necessary for certain applications.

Confirmation and Calibration Process
Calibration involves assessing the quality of the weighing instrument in its operational environment. It provides temporary information, while a series of calibrations offers time-dependent data. The calibration method should yield precise and comparable results.

Calibration Program
A structured calibration program calculates deviation and measuring tolerance, storing historical data for monitoring. It allows users to select appropriate calibration methods and provides comprehensive information on measuring capability.

Purpose of Calibration
Calibration confirms the correct function of weighing instruments, requiring users to define limits for deviation and measuring tolerance. External factors affecting instrument performance must be considered.

Calibration Certificate
The calibration certificate serves as evidence of performed calibration, aiding in quality system audits. It ensures traceability and helps evaluate measuring tolerance.

Conclusion
Calibration is essential for maintaining measurement systems and achieving desired measurement quality. Key considerations include procedure selection, information interpretation, and adapting procedures based on calibration data.
