Claim:
1. A system for testing a dielectric layer disposed over a capacitive sensing device, the capacitive sensing device having multiple electrodes, the system comprising: a test probe disposed over the dielectric layer such that the dielectric layer forms a dielectric body positioned between the test probe and the capacitive sensing device; and a power supply that supplies a voltage to the test probe, wherein the voltage energizes multiple capacitive regions within the dielectric body formed by the test probe and the multiple electrodes, wherein each of the multiple capacitive regions, when energized, has a measurable capacitance value used to determine a compensation value; and a storage device, wherein when the measurable capacitance value exceeds a threshold capacitance value defining an outlier capacitance value, the storage device applies the compensation value to the outlier capacitance value, the compensation value altering the outlier capacitance value to be within the threshold capacitive value.
