T3Ster-Master displays smoothed curves as ascending or descending ones depending on the direction of the voltage change during the measurement. Zth curves are normally ascending ones.
When making a report it is often required that the curve be ascending or descending in order to represent heating or cooling. Curves can be swapped using the Invert selected curves item of the Manipulate menu.
The curves can be selected by clicking the given curve in the view or on the name of the curve or the line preceding it in the legend key (Figure 4-51).
