(750) = USEr User’s definition〔11 polygonal line settings〕
The default value at shipping is (700) = (Lin) Linear. When user’s
definition (USEr) is set, the following 11 data can be set
*7
.
However, the setting range is between -20.0 and 120.0%.
Definition by user can be set by value (vALU) and operation (ACt).
