That is, the CPU 1-1 determines that the measured value is 40
In the case where the display range corresponds to the display range of ~ 50 ° C, the main color (color at 50 ° C) is red and the sub color (color at 40 ° C) is white with reference to the color calling setting table shown in FIG. Then, the RGB values corresponding to the measured values are calculated by the following equation (1).

If the measured value is larger than the first display range, the measurement target is displayed with the RGB value of the first color (red) (step 507). If the measured value is smaller than the first display range, the process proceeds to step 508, and it is determined whether the measured value is in the third display range (0 to 10 ° C). Third
If it is within the display range, the process proceeds to step 509, and the ratio between the maximum value and the minimum value of the display range and the measured value is calculated. Then, the RGB values of the third color (blue) corresponding to the minimum value of the third display range and the second color (white) corresponding to the second display range (10 to 40 ° C.) are proportionally distributed. Display color RGB

If it is determined in step 508 that the measured value is not in the third display range, the process proceeds to step 512. In step 512, it is determined whether the measured value is smaller than the third display range, that is, whether it is equal to or less than the minimum value (0 ° C.) of the third display range. If the measured value is smaller than the third display range, the measurement target is displayed with the RGB value of the third color (blue) (step 513). If the measured value is larger than the third display range, that is, if the measured value is within the second display range, the measurement target is displayed with the RGB value of the second color (white) (step 5).
