Abstract: An apparatus and method for measuring potentiometric electrode impedance for diagnostic purpose while continuously reading the results of the process value. A square wave is applied to an external circuit (78, 84), which in turn is coupled to an electrode assembly (13) output through a capacitor (52). The output of the electrode (13) is converted into a pulse width modulated signal and sampled. These sampled values are used to calculate the impedance and process output value.
