Abstract:
1. A method of measuring a quantity of a substrate included in a 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; determining that the sample liquid is insufficient when the electric current from the second group of electrodes does not exceed a predetermined threshold within a given lapse of time after the electric current from the first group of electrodes exceeds the predetermined threshold; and when it is determined that the sample liquid is insufficient, outputting, to outside of the measuring device, an indication to have a user add sample liquid to the sample supplying path.
