Smoothing will take a running average of five consecutive data points, two on either
side of the current wavelength, and plot those. For example, the absorbances at 455,
456, 457, 458, and 459 nm are averaged and plotted at 457 nm. Then the absorbances
at 456, 457, 458, 459, and 460 are averaged and plotted at 458 nm.
Note:
After the data are printed, you can go back to the Ready screen and turn on or off
the smoothing feature and then plot the same data again. First go to the Ready screen, choose
Options, reset the Smoothing and then press Print.
