Abstract
A first measurement device is a measurement device for measuring the concentration of a target substance in a sample deposited on a biosensor, and more particularly is constituted such that at least two kinds of voltage of mutually different levels are applied at mutually different timings to the electrode system of the biosensor, and the concentration is corrected on the basis of the amount of change in the current value.

26. A measurement device for measuring the concentration of a target substance in a sample deposited on a biosensor having first and second electrode systems, the measurement device comprising:
-
a mounting component configured to be mounted with the biosensor; a voltage application component configured to perform a first voltage application operation of applying a first voltage to the first electrode system, and a second voltage application operation of applying at least two kinds of second voltage of mutually different levels at mutually different timings to the second electrode system; a concentration acquisition component configured to acquire the concentration of the target substance on the basis of the current value of the first electrode system when the first voltage is applied; and a correction component configured to correct the concentration acquired by the concentration acquisition component on the basis of the amount of change in current value of the second electrode system between the at least two different timings during the second voltage application operation. - View Dependent Claims (27, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40)
