When you wish to show the readings as compared to
some standard reading, the normalize function allows you

readings will be shown as a ratio to the reference
reading. For instance, if you normalize the reading at an
energy of 1.5mJ, then subsequent readings will be with
ratio to that, i.e. if the energy at that point is 2mJ, the
