2) preparation work before measurement and calibration;
adjusting the opening degree of the vertical roller/guide ruler to be maximum, adjusting the total length of the measuring ruler to be 2-10 mm smaller than the opening degree of the vertical roller/guide ruler, and then extending the measuring ruler into a position to be measured between the vertical roller/guide ruler; in the measuring and calibrating process, the support is held by an operator in a hand or fixed on a cross beam of the rolling mill through an auxiliary support, and the measuring scale is kept horizontal through a level gauge;
