Electronic Weighing Scale Calibration Guide
Calibration is the process of comparing the weighing machine with certified standard test weights and adjusting the displayed value so that the weighing result remains within the permissible Tolerance . Regular calibration improves product quality customer confidence and measurement Accuracy . Industries working under ISO 9001 ISO 17025 GMP and NABL standards are generally required to calibrate their weighing instruments Periodically. Proper calibration also helps detect problems in load cells indicators ADC circuits and mechanical structures before they become major Failures.
Standard Calibration Procedure
- Place the weighing machine on a perfectly level surface.
- Allow the machine to warm up for 15–30 minutes.
- Check that the weighing platform is clean.
- Verify Zero Display.
- Use Certified Standard Test Weights.
- Perform Span Calibration if required.
- Check repeatability using multiple readings.
- Verify Linearity at different weight points.
- Perform Corner Load Test.
- Record all calibration observations.
