The current level Measurement Output from the device is presented with an
arrow at the top of the plot.
Normally, the measurement output points directly at the surface echo peak,
but if, for instance, the tank is empty, and there is no surface echo peak
detected, the Measurement Output is still presented indicating the distance to
the tank bottom.
In Figure 7-10, the interface output peak is pointing to the linear distance
based on corrections for the dielectric of the material. The actual interface
peak is at the electrical distance.

ModeTab The View/Record Mode tab presents a plot of the current tank conditions.
Each radar echo is displayed as a peak in the signal plot.
