In step S92, a process for determining whether or not the dog flag is “1” is executed. If the dog flag is “1”, the process proceeds to step S93, and if the dog flag is not “1”, the process proceeds to step S94.
In step S93, a process for correcting the calculation result obtained in step S91 according to the characteristics of the blood of the dog is executed. In this process, for example, a process of multiplying the obtained hematocrit value by 0.97 is executed.

In step S94, processing for determining whether or not the cat flag is “1” is executed. If the cat flag is “1”, the process proceeds to step S95, and if the cat flag is not “1”, the process proceeds to step S43 (FIG. 17).
In step S95, a process of correcting the calculation result obtained in step S91 according to the characteristics of cat blood is executed. In this process, for example, a process of multiplying the obtained hematocrit value by 0.88 is executed.

  The analyzer of the present invention includes a sound source in the control board unit 9 and is configured to reproduce a dog cry from the sound source in the dog measurement mode and a cat cry in the cat measurement mode. May be. For example, in step S39 (FIG. 17), the dog picture 56a is displayed and the dog cry is reproduced from the sound source. In step S40 (FIG. 17), the cat picture 56b is displayed and the cat cry from the sound source. May be played back. As a result, the user can know that the measurement has been completed by crying, and can check the selected measurement mode.

  The analyzer of the present invention may display a dog picture 51a or a cat picture 51b on the main screen 31 corresponding to the selected measurement mode. For example, the dog flag and the cat flag are set in step S6 (FIG. 16), the dog picture 51a is displayed in the area between the print instruction area 43 and the start button display area 50 on the main screen 31, and the dog flag and cat flag are displayed in step S8. The cat flag may be set and the cat picture 51 b may be displayed in an area between the print instruction area 43 and the start button display area 50 of the main screen 31. Thereby, on the main screen 31, when the dog measurement mode is selected, the dog picture 51a is displayed, and when the cat measurement mode is selected, the cat picture 51b is displayed. Accordingly, since the user can confirm the selected measurement mode before starting measurement, it is possible to prevent the measurement from being started in the wrong measurement mode.

  Moreover, the analyzer of this invention may change the picture displayed on the display 3 according to the progress of the measurement operation. For example, in step S21 (FIG. 17), a picture of a sleeping dog is displayed. In step S27, a picture of a dog with his face raised while sleeping is displayed. A picture of a dog may be displayed, and a picture of a dog standing in step S39 may be displayed. In this case, the dog picture may be displayed at the same position on the screen, or may be displayed at a different position.

  Moreover, the analyzer of this invention may display a character on the display 3 according to the progress of the measurement operation. For example, in step S21 (FIG. 17), the character “ONE” is displayed, in step S27, the character “ONE ONE” is displayed, in step S34, the character “ONE ONE ONE” is displayed. The characters “one-one-one-one” may be displayed.
