Why is calibration mandatory?
Eliminating Installation Errors: Even sensors of the same model can have slight differences in sensitivity and zero-point output. Failure to calibrate after replacement will lead to inaccurate weighing results.
Restoring System Linearity: Calibration is necessary to re-establish the input-output linearity between the new sensor and the original mechanical structure, ensuring accurate readings.
Meeting Regulatory Requirements:According to Chinese metrology regulations, weighbridges and other weighing equipment must undergo mandatory calibration after replacing core components (such as sensors); otherwise, the replacement is not legally valid.
Preventing Long-Term Drift: Uncalibrated systems may experience zero-point drift and increased hysteresis errors during use, affecting stability.
