9-25. Correcting the digital tension output (KE-430HX, BE-438HX)
・ The procedure for correcting the tension (output) from the digital tension
involves carrying out the procedure of measuring the actual upper thread
tension and entering the four measured values using the operation panel.
・ The standard values for the four tensions for the digital tension vary for each
measurement as shown in the table at right.
By entering the actual measurement values each time, the digital tension
output will be automatically corrected, and the tension that corresponds to the
setting can then be obtained when sewing.
