Claim 9:
10. An analyzer comprising:
a preparation unit configured to prepare a plurality of specimens that include samples of calibrator, respectively, at different dilution rates;
a measurement unit configured to repeat a measurement at a number of the different dilution rates to measure each of the plurality of specimens to obtain sets of time series data corresponding, respectively, to the different dilution rates;
a controller configured to repeat an analysis at the number of the different dilution rates to analyze each set of time series data to derive, and store in a memory, a first set of calibration curve points corresponding, respectively, to the different dilution rates; and
the controller further configured to, subsequent to storing the first set of calibration curve points in the memory, perform a point correction process for each initiation of the point correction process, wherein the point correction process is executed to correct a calibration point in the first set of the calibration curve points and comprises following steps (a), (b), (c), (d), (e) and (f):
(a) displaying a point selection screen that shows the first set of calibration curve points retrieved from the memory for a selection of one point from the first set of calibration curve points to be corrected;
(b) in response to a selection of one calibration curve point from the first set of calibration curve points, displaying an input screen that requests an input of a rack identifier of a specimen rack and a position identifier of an insertion position in the specimen rack;
(c) preparing a re-measurement specimen that includes a quantity of the calibrator at a dilution rate corresponding to the selected one calibration curve point, wherein the re-measurement specimen is prepared from the calibrator that has been inserted by a user in the identified insertion position of the identified specimen rack;
(d) measuring the quantity of the calibrator in the re-measurement specimen and obtaining a new set of time series data corresponding to the selected one calibration curve point;
(e) analyzing the new set of time series data to derive a new calibration curve point corresponding to the selected one calibration curve point; and
(f) replacing the selected one calibration curve point in the memory with the new calibration point to update the first set of calibration curve points to a second set of calibration curve points.
