PURPOSE:To display a discrimination result on a display device, by a method wherein a measured value is stored in a memory and an average value is calculated to be compared with at least one preset reference value while it is discriminated whether the average value is within a normal range. CONSTITUTION:When a power source switch is turned ON, a measuring apparatus is started and, in a step 4(ST4), it is waited that a measuring switch is turned ON. When the measurement in ST5 has been finished, ST6 is taken; when an average switch is turned ON, the processing on and after ST8 advances. An arithmetic mean value is calculated from the measured value obtained in the past in ST8 and displayed on the numerical value display part 31 of a display device 3. The average value is compared with a reference value if ST10 and, when abnormality is discriminated, an abnormal mark 36a is displayed in ST11. Further, abnormal marks 36b, 26c are successively selected and displayed correspondingly to the degree deviated from a normal range. |
