Special cases
• Jumps/discontinuities can be displayed by parameterising two successive x values the same
way. A jump is only valid if a valid pair of variates exists after that, otherwise the extrapolation
is executed starting from the last valid pair of variates.
[5-131] Example: Characteristic in the characteristic mode 0 (entire range) with jump
• If only one point X1 is defined in the negative range, X2 exists with the Lenze setting "0" as valid
point (X2 > X1) and both points form a line:
[5-132] Example: Characteristic in characteristic mode 0 (entire range) with only one defined point and X1 < 0
