How to eliminate the systematic error in the experiment?

The systematic error is also called the regular error. It is that under certain measurement conditions, when the repeated measurement is performed on the same measured size, the magnitude and sign of the error value (positive or negative value) remain unchanged; or when the condition changes, it changes according to a certain law. Error; the […]
