Standard line specification
method
Defining two standard lines by assuming the measurement data as
the standard waveform and specX% and −Y%
Any shape is defined by the user.
Defining two standard lines of any shape and the shape obtained by
inverting the sign (time-axis waveform only)
By data type for standard line (invalidated if differentiated or
integrated)
Shape method NG if any standard line is overrun or underrun
