2) Correction value [%] to be employed when the sewing machine runs at 150 sti/min can be set by pressing
❸ . This value can be increased / decreased with ❾ .
When you have selected ❸ , the sewing machine is able to perform sewing at the maximum sewing speed
of 200 sti/min with needle thread tension

（ Example of use ）
In the case the correction is made as shown in the
figure
・ If the sewing speed is "200 sti/min", the needle
thread tension will be corrected by "150 %",
from "70" to "105".
・ For the sewing speed that is not shown on the
scale, the correction along the inclination of the
line chart will be applied.
If the sewing speed is "600 sti/min", the needle
thread tension will be corrected by "128 %",
from "70" to "89".
