, And the CPU 7 has both functions of a processing unit and a control unit.

The input terminal 1 is for data input, and data representing a voltage waveform, a current waveform, and the like is input to the input terminal 1. The input data is sent from the input terminal 1 to the input unit 2. When receiving the data from the input terminal 1, the input unit 2 outputs the data to the CPU 7 and the RAM 5.

The operation unit 3 is an input device having a plurality of keys. The operation unit 3 may be a keyboard. For example, when the display unit 11 is formed of a display such as a liquid crystal panel, the operation unit 3 is provided in a predetermined display area so that a key can be selected by a mouse pointer or a touch panel. You may.

Various instructions such as an instruction for reading a file from the floppy disk drive 4 or the RAM 5 and an instruction for writing a file to the floppy disk drive 4 or the RAM 5 are given to the operation unit 3 by a key operation of the user. Is entered. The operation unit 3 outputs the input instruction or the like to the CPU 7 as an instruction signal.

The floppy disk drive 4 reads a file recorded on a floppy disk (FD) and outputs the read file to the CPU 7. Conversely, when receiving the files and data from the CPU 7, the floppy disk drive 4 writes these files and data to the floppy disk. At this time, the floppy disk drive 4 records the data as a file on the floppy disk according to an instruction from the CPU 7.

The RAM 5 stores data from the input unit 2 and CPs.
When a file is received from U7, these data and files are stored in the same manner as the floppy disk drive 4.

The clock section 8 constantly measures the time from the beginning to the end of the day, and upon receiving a request signal from the CPU 7, generates a time signal representing the time when the request signal was received. The clock unit 8 converts the generated time signal into C

After step S1, the CPU 7 sets the clock unit 8
When a time signal is received from (step S2), display control for displaying the time indicated by the time signal is performed on the display unit 10 (step S3). By the step S3, for example, as shown in FIG.
-04-07 15:37:48 "is displayed. In this display, “98-04-07” is the date when the error occurred, and “15:37:48” is the time when the error occurred.

Step S3 ends, and the CPU 7 receives the elapsed time signal from the timer section 9 (step S4).
After step S4, the CPU 7 controls the display unit 10 to display the elapsed time indicated by the elapsed time signal (step S5). By step S5, for example, as shown in FIG.
-00-00 00:01:12 "is displayed. In this display, “00-00-00” is the date indicated as the date when the error occurred after one day,
“00:01:12” is the elapsed time.

When step S5 is completed, the CPU 7
It is checked whether a key of the operation unit 3 has been operated (step S6). When the key operation of the operation unit 3 is not detected, the CP
U7 receives the elapsed time signal from the timer unit 9 for each unit time, and repeats the processing of steps S4 to S6.

When the key operation of the operation unit 3 is detected in step S6, the CPU 7 controls the display unit 10 to erase the error display from the liquid crystal panel 10A (step S7). When step S7 ends, the CPU 7 ends the abnormality occurrence processing.
