Abstract
Systems and methods are provided to determine a capacitance of an electrochemical biosensor test cell of a test strip via determination of a phase angle between an output signal and input oscillating signal from the electrochemical test cell with measurement of an amplitude of the output signal from the electrochemical test cell along with conversion of the measured amplitude into a complex impedance of the electrochemical test cell based on the oscillating signal, phase angle and electrical resistance between the test cell and the connectors to derive a capacitance of the electrochemical test cell based on the complex impedance and predetermined frequency of the electrochemical test cell.
