ABSTRACT:
An apparatus for testing an alcohol concentration sensor used in measuring an alcohol concentration of a fluid containing alcohol. The alcohol concentration sensor includes a capacitive probe having a capacity dependent upon the alcohol concentration of the fluid, and a circuit sensitive to the capacity of the capacitive probe for producing an output signal indicative of a sensed alcohol concentration. The apparatus comprises a plurality of capacitors having different capacities each corresponding to a predetermined alcohol concentration. A selected one of the capacitors is connected in parallel with the capacitive probe. When the selected capacitor is connected with the capacitive probe, the output signal is read.
