Abstract

PURPOSE:To attain accurate measurement, regardless of the location where warp occurred, by positioning multiple leg parts by shielding them along supporting beams, and positioning a dial gauge between or outside of them far measurement. CONSTITUTION:When measuring warp in the middle of a board material 11, with its center paint P1 as a measurement paint, the fixing position of a two-leg part 15 on a supporting beam 13 is adjusted so that a dial gauge 14 is situated about the center of the two-leg part 15, and a measurement device 12 placed an the board material 11. The scale indication when a measurement piece 14A of the gauge 14 contacts to the measurement point P1 is read. So that the warp of the board material 11 is measured. When the warp at one end of the board material 21 is measured, division parts 13A and 13C of the supporting beam 13 is discounted from the gauge 14, a division part 13D is connected to the division parts 13A or 13C, and the two-leg part 15 is moved to one side of the gauge 14 for measurement. The two-leg part 15 and the gauge 14 are dismounted from the supporting beam 13 is divided into 13ABD, for compact storage.
