Abstract
There is provided a sensor testing method including: applying at least one of a first voltage that obtains a response caused by a substance and a second voltage that either obtains no response or substantially no response caused by the substance across a first electrode and a second electrode of a sensor; measuring current flowing between the first electrode and the second electrode; and determining whether or not there is a defect present in the sensor based on a quantity related to an amount of change per specific period of time of a current measured when the first voltage and/or the second voltage have been applied.

13. A sensor testing method comprising:
-
applying to a reagent layer of a sensor section at least one of a first voltage across a first electrode and a second electrode to generate a response current by reaction of a reagent present in the reagent layer with a target substance in a sample liquid and a second voltage that results in no response current or substantially no response current, where the sensor section comprises the reagent layer, an electrode section comprising the first electrode, the second electrode and an external layer membrane for making contact with the reagent layer; measuring the response current flowing between the first electrode and the second electrode; and computing a time required for an amount of change in the response current per specific amount of change in time resulting from the application of the first voltage to reach a value in a predetermined first specific range prior to when the response current reaches a steady state for determining whether there is a defect present in the external layer membrane, or computing a time required for an amount of change in the response current per specific amount of change in time resulting from the application of the second voltage to reach a value in a predetermined second specific range prior to when the response current reaches a steady state for determining whether there is a defect present in the external layer membrane. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23)
