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, andthe 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, andcalculate 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, anddetermine 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, andif 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.

Abstract
With this biological sample measuring device, the determination section performs measurement at specific intervals in a first measurement period from the start of measurement until a first time, and performs measurement at specific intervals in a second measurement period that comes after the first measurement period, calculates the difference between the measurement values in corresponding specific periods, and finds a plurality of first difference determination values, on the basis of a plurality of current values measured in the first measurement period and a plurality of current values measured in the second measurement period, finds a second difference determination value by finding the difference at specific intervals in the plurality of first difference determination values, and determines whether or not a reagent movement error and/or exposure error of the biological sample measurement sensor has occurred, on the basis of the first and second difference determination values.
