1. A method for testing a variable capacitance measurement system, the system including a voltage source, a variable capacitance sensor, and a processing circuit to process information output by the variable capacitance sensor, the method comprising: replacing the variable capacitance sensor of the measurement system with an electronically controllable simulation device having a fixed capacitor; modeling the electro-physical behavior of the variable capacitance sensor to generate a voltage signal, the voltage signal able to cause similar electro-physical values generated by a variation of a capacitance of the variable capacitance sensor when applied to the fixed capacitor; and testing the measurement system with the voltage signal to obtain characteristics of the variable capacitance measurement system.
