Abstract: Measuring the electrical resistance of a resistive body, in particular a reservoir containing a printing product such as ink. According to the invention, the resistive body is used to define a capacitance arrangement formed from a capacitive branch which includes a capacitor electrically connected to the resistive body and this is incorporated in a resonant circuit that includes a variable capacitor. The resonant circuit is supplied with a fixed frequency, and as the capacitance of the variable capacitor is varied the peak of the signal is sought. The amplitude of the peak is representative of the resistance of the resistive body.
