Abstract:
1. A biosensor measurement machine comprising: a voltage application unit for applying a voltage to a biosensor chip; a measurement unit for measuring a current or a charge generated by the voltage application unit; and a control unit for determining whether a measurement should be continued, based on a current value or a charge value measured by the measurement unit, wherein the control unit is configured to: compare the current value or the charge value with a reference value to determine whether the measurement should be continued, terminate the measurement of the current value or the charge value either when it is determined that the current value or the charge value exceeds the reference value, or after a predetermined time has passed, whichever occurs first, and, perform a measurement of a chemical substance to determine the concentration of the chemical substance based on said current value or charge value measured immediately prior to termination of the measurement as measured by the measurement unit.
