Claim Text:
1. A biological sample measuring device, comprising: a sensor mounting section to which a biological sample measurement sensor is mounted, wherein a reagent is to be placed on the biological sample measurement sensor; a main body case having the sensor mounting section; a measurement section that is connected to the sensor mounting section; a controller that is connected to the measurement section; and a determination section, a calculating unit, and a display section that are connected to the controller; and a memory section that stores a first upper threshold, a first lower threshold, a second upper threshold, and a second lower threshold, the memory section is connected to the determination section; wherein the measurement section is programmed to measure current values at intervals in a first measurement period, and is programmed to measure at intervals in a second measurement period that comes after the first measurement period, and the calculating unit is programmed to: calculate a plurality of first difference determination values by subtracting the current values measured at the intervals in the first measurement period from a plurality of current values measured at the intervals in the second measurement period, respectively, and calculate a second difference determination value by subtracting one of the first difference determination values from another of the first difference determination values; and the determining section is programmed to: compare the plurality of first difference determination values with both the first upper threshold and the first lower threshold to determine a first comparison result, compare the second difference determination value with both the second upper threshold and the second lower threshold to determine a second comparison result, and determine that an error exists if the first comparison result fails to satisfy a first condition and the second comparison result fails to satisfy a second condition, and if an error is determined to exist, determine that the error is an exposure error if the first comparison result satisfies a third condition and the second comparison result satisfies a fourth condition, and determine that the error is a reagent movement error if the error is not determined to be an exposure error.
