In the case of another measurement point, a flag is set during measurement at another point (step b3), data is taken in at another point (step b4), and the process proceeds to step b1.

In step b2, if it is not another measurement point, a measurement NG (measurement failure or measurement impossible) processing routine is executed (step b5), and the measurement item flag is set to complete (step b6). Here, the measurement NG (measurement failure or measurement impossible) routine is as follows. ~ 5. The procedure consists of. 1. Re-measurement point is measurement NG (No in step b2)
If Yes, the following 2. Go to No
In case of 4. Proceed to. 2. At the time of measurement, the colored circle at the measurement position that became NG on the screen blinks alternately red and blue, or “Re-measure” is displayed in the empty space on the screen while blinking red, and on the screen Leave the measurement value field of
Blink the displayed value and 3. I will proceed. 3. The data after the re-measurement by the measurer is acquired and the process proceeds to step b1. 4. "Identification number" and "unusable due to defective product" are displayed on the screen, individual identification data and defective contents are printed on the tag 15, and the tag 15 can be separated so that it can be attached to the DUT 11. 4. Output in a state or send data to the identification and transport robot 16 that allows the defective object to be measured 11 to be discarded. Proceed to. 5. The part number, identification number, defective part, and measurement data of the part are stored as a set of data in the database in the personal computer, the server, or the database of the host computer, and the process proceeds to the end.

Next, in step b7, it is judged whether or not all the measurement items are completed. If all the measurement items are completed,
When the measurement is completed and all the measurement items are not completed, it is determined whether or not the measurement is being performed separately (step b8).

When the measurement is performed at the separate place, the flag for measuring the separate place is reset (step b9), the data of the original place is fetched (step b10), and the process proceeds to step b1.
In step b8, if the measurement at the separate place is not being performed, the process proceeds to the next measurement item (step b11), the flag for measuring the next measurement point is set (step b12), and the data of the next measurement point is fetched (step b13). ).

It should be noted that in the above embodiment, the parts are used as the object to be measured in the machine factory, and the individual identification data for identifying the individual parts and the solid measurement result data which is the measurement result data for each individual part.
