When the power button 23 is operated in an on state in order to operate the external display device 20 according to the present invention, the power of the power supply unit 31 is supplied to the system to start the operation. In this case, when the power is supplied, the MCU 32 turns on the power lamp 25 and initializes the system, and then is in the standby mode (step 101).

In this state, the user operates the mode setting button 26 of the operation unit 29 to set the operation mode, and according to the mode setting to perform the corresponding operation.

That is, when the user sets the measurement range input mode (step 102) by operating the mode setting button 26 for setting the error correction limit range of the measured value, the set value is changed by the up / down buttons 27 and 28. The mode of inputting is performed (step 103), and when the output mode mode (step 104) is set, the mode of setting the output type on the up / down buttons 27 and 28 is performed (step 105).

On the other hand, when operating the mode setting button 26 to set the measurement mode (step 106), the MCU 32, the response signal (REQ) to the MCU (4) of the microdisplacement measuring mechanism 10 through the first cable 34 The MCU 4 transmits the measured data value measured by the measurement unit 3 by the response signal to the MCU 32 of the external display device 20 through the data output unit 6. Done.

In this case, the MCU 32 of the external display device 20 continuously collects (step 107) the measured data values transmitted from the data output unit 6 of the microdisplacement measuring instrument 10 and stores the measured values. When the data storage is completed (step 108), the data value collected through the display unit 22 is displayed and transmitted to the computer 40 through the communication port 33 (step 109).

At the same time, when the collected data value is out of the set range and the comparative analysis (step 110), the control signal is output (step 112) to complete a series of processes of sending an alarm sound through the speaker 24, thereby resulting in a long distance. In addition, it is easy to check the measured value, and the data can be stored continuously so that the comparative analysis of the measured value is possible, as well as the repeated collection of the data in connection with a computer, the data can be compared and the error can be detected. On the other hand, when the measured value is out of the setting range, the user can quickly notify the user by outputting a control signal such as an alarm sound through the speaker.

FIG. 5B is a flowchart illustrating an interrupt operation when a clock is not received from the data output unit 6 of the microdisplacement measuring instrument 10 while the measurement mode is executed in the external display device 20. If the clock is not received from the data output unit 6 in the process, it is determined whether the collected temporary data is in an initialized state (step 121), and if it is determined that the accumulated data exists, the temporary data is accumulated (step 123). In the case of the initialization state without the temporary data, the response signal REQ is continuously transmitted to the MCU 4 of the microdisplacement measuring instrument 10 (step 122).

Thereafter, when it is determined that the accumulation of the temporary data is completed (step 124), an abnormal occurrence of the microdisplacement measuring instrument 10 is accumulated by completing a series of interrupt processes for storing and initializing the accumulated data (step 125). This is to prevent data loss.
