Abstract

A method for testing a variable capacitance measurement system including a fixed voltage source, a variable capacitance sensor, and a circuit to process information output by this sensor. The method connects an electrically controllable electronic simulation device to replace the variable capacitance sensor, models the electrophysical behaviour of the sensor, and tests the system.
