A calibrated weighing system is a system that has been thoroughly inspected and tested, under the supervision of the FPS Economy, checking that it meets all legal requirements. Calibration or recalibration ensures that the data are always correct. It is recommended that a weighing system be periodically calibrated to ensure the accuracy of the volumes weighed at all times.

To perform this calibration, we must always have a known weight (to be provided by the customer) to ensure the accuracy of the test.
