・1
st
Torque needs to be set lower than SNUG Torque [1
st
Torque < SNUG Torque] when a
spindle synchronizes with other spindles at 1
st
Torque or when you want to improve
the accuracy of the angle judgment. (Due to spindle relaxation during synchronizing)

・Set 1
st
Angle higher than the Final Angle High Limit and 2
nd
Torque equal to Full Scale
Torque.
