When done, the program will show the data and provide you with an oppor-
tunity to plot it (Figure 18-20). You can also view the current LED source cal-
ibration later by selecting "_LED Source - Plot Curve".
To actually implement this calibration data, you must respond by pressing Y
when asked (Figure 18-21).
