When the remaining amount of the reagent in the reagent bottle 10 is larger than the dead volume set value in step 803, the process returns to step 802, and the reagent of the reagent bottle 10 is used when the use of the reagent is requested in the next measurement. To be done.
- step 803 If the remaining amount of the reagent in the reagent bottle 10 is less than or equal to the dead volume set value in step 803, it is confirmed whether or not the automatic mode is set for the dead volume (step 804).
- the automatic mode is not set for the dead volume in step 804, the measurement from the reagent bottle 10 is completed and the dead volume set value is not changed (step 808).
- step 804 when the automatic mode is set, the dead volume setting is performed from the test number in which the reagent in the reagent bottle 10 is preset to the dead volume setting value and the remaining test number (for example, 30 tests) is added.
- the remaining test number for example, 30 tests
- the number of remaining tests obtained from the liquid level detection value by the liquid level sensor (reagent remaining amount information 1) and the remaining test number calculated by soft count (reagent remaining amount information 2) are compared with each other, and it is determined whether or not there is a difference of a certain amount or more (whether or not there is a remaining amount skip) based on the information stored in the storage unit 23 (step 805).
- step 805 if there is no difference between the remaining test number obtained from the liquid level detection by the liquid level sensor and the remaining test number calculated by the soft count, that is, if there is no remaining amount skip, the inside of the reagent bottle 10 The measurement by the reagent dispensing is completed, and the dead volume setting value is not changed (step 809).
- step 805 when the difference in the remaining test number occurs in the reagent in the reagent bottle 10 and the remaining test number obtained from the liquid level detection by the sensor is larger than the remaining test number calculated by the soft count by a certain amount or more. That is, when the remaining amount is skipped, the dead volume setting value of this type of reagent is changed by adding a +5 test (change width value) to the current setting value (step 806), and the changed information is stored in the storage unit 23. Store in. Then, the measurement by dispensing the reagent in the reagent bottle 10 is completed (step 807).
- the dead volume setting value since the dead volume setting value is automatically changed, the user can save the trouble of manual setting (changing the dead volume setting value). Further, when it is not desired to increase the amount of discarded reagent beyond a certain line, the upper limit value for changing the dead volume may be set. It is also possible to change the change width value of this dead volume from the +5 test to another value. This can be changed by the dead volume change width setting portion 702 shown in FIG. By operating this dead volume change width setting portion 702, the current dead volume change upper limit value is displayed on the dead volume change width setting portion 702, and the displayed value can be changed.
- the same effect as that of the first embodiment can be obtained, and the number of remaining tests and soft count obtained from the liquid level detection by the liquid level detection mechanism (liquid level sensor) near the dead volume set value. Even if there is a discrepancy between the remaining test number calculated by (counting (counting) the reagent dispensing times of the reagent dispensing mechanisms 7 and 8 by the control unit 25), that is, when the remaining amount is skipped, the automatic Since the dead volume set value can be changed to an appropriate value, the user does not need to manually change the dead volume set value, and the work load on the user (operator) can be reduced.
- step 805 the set value of the number of tests for determining the presence / absence of remaining amount skip is not limited to 30 tests, and the user may arbitrarily change it.
- the remaining amount of the reagent may be managed and set not by the number of tests but by the volume of the reagent or the liquid level height.
- changing the dead volume setting has been described as an example of means for solving the problem.
- the amount of the reagent dispensing probes 7a and 8a that plunge into the liquid surface in the reagent bottle 10 may be changed.
- the plunge amount setting portions 204 (FIG. 12), 304 (FIG. 13), and 404 (FIG. 14) are displayed, and each measurement item, each reagent container shape, and each reagent wettability is displayed.
- the amount of the reagent dispensing probe that plunges into the liquid surface may be set. Further, the amount of plunge may be set together with the dead volume setting value.
- the amount of protrusion to the liquid surface in the reagent bottle 10 may be set to be increased by 0.01 mm.
- the user sets the value within the range specified by the manufacturer, such as 0 to 0.3 mm.
