CALIBRATION METHOD AND DEVICE

摘要

A calibration method and device calibrate a signal to be calibrated and measured. The signal to be calibrated and measured is outputted by a linear measurement system in a test stage. The method includes inputting a default input signal to the linear measurement system to obtain a default measurement signal; determining a linear strength between the default measurement signal and the default input signal; obtaining a calibration formula according to linear retrogression to calibrate the signal to be calibrated and measured, thereby obtaining a calibrated value and effectuating precise linear measurement.
