Abstract:
1. A method of measuring a quantity of a substrate included in sample liquid, comprising the steps of: providing a biosensor which includes: providing a measuring device which includes: inserting the biosensor into the supporting section of the measuring device; applying a voltage with the driving power supply to a first group of electrodes including the first electrode and the second electrode; applying a voltage with the driving power supply to a second group of electrodes including the third electrode and one of the first electrode and the second electrode; and determining that the sample liquid is sucked from the air hole by mistake when the electric current from the second group of electrodes exceeds a predetermined threshold before the electric current from the first group of electrodes exceeds the predetermined threshold and when the electric current from the first group of electrodes does not exceed the predetermined threshold within a given lapse of time.
