Fix capacitor readings

[Xalcon]

The readings in the tooltip currently assumes that the value is the actual increase.
This is not the case - the value is just an indexer into an array of scaling values that get multiplied by this value.

Depending on the machine there are different scalers. Therefore, it is not feasable to add all the information to the Tooltip. We need an analyzer gui.
