NOTE
If a slow response value (time constant) is set,
responsiveness is adversely affected and the peak
height is decreased, but the smaller the width at half-
height, the larger is the extent of the decrease in the
peak height.
Here, as a guide, the situation where a width at half-
height that decreases the peak height by 10 % can be
used has been shown for each response. The
relationship between peak's half-height and decrease in
peak height is shown in the graph to the right.
Fig. 4.4Note that even if the responsiveness is adversely
affected and the peak spreads, the peak area doesn't
change.
