Type the pressures and jack readings at each end, or leave the sheet empty to print a blank format. The jack reading difference (after − before draw-in, col. 6 and 13) is worked out per row. Below the table, Total Elongation = col.6 + col.7 + col.13 + col.14 (column totals, as printed on the sheet), Slip at both ends = col.9 + col.15, and Net Elongation = Total Elongation − Slip. Corrected pressure, correction factor and total elongation per row are typed. Typed values are saved for this project.
