An area for displaying parameter data, an area 51d is an area for displaying related information such as a person in charge, a date, a message, and the like.
[0027]
It is assumed that the above-described f1 function key 22a is pressed while the basic screen 51 is displayed on the display unit 21. In the flowchart shown in FIG. 4, it is determined in the determination step S11 whether the f1 function key 22a has been pressed. If it is determined in determination step S11 that the f1 function key 22a has been pressed (YES), the display content of the display unit 21 will be a menu 1 screen 61 (hereinafter, referred to as a menu 1 screen 61) shown in FIG. 7 (step S12). ). On the menu 1 screen 61, a list of menu contents is displayed. The menu 1 screen 61 is a menu for setting items related to measurement. The menu 1 screen 61 is an initial setting screen. On the menu 1 screen 61, a line cursor (shown by oblique lines) 65 is displayed at the same position as the previous time (step S13). In this case, the line cursor 65 is positioned at one line of the condition setting 1. In FIG. 7, for convenience, the line cursor 65 is indicated by oblique lines, but is displayed in a specific color on an actual screen. On the other hand, if the f1 function key 22a is not pressed in the determination step S11 (NO), the basic screen 51 is maintained, and the parameter setting menu (area 51c) is maintained (step S14). The operation related to the parameter setting menu will be described later with reference to FIG.
[0028]
In the display of the parameter setting menu in the area 51c in FIG. 6, "gain" means sensitivity (amplification), and "beam path" means the propagation distance of ultrasonic waves (calculated from sound speed and propagation time). , “Echo height” means the height of the ultrasonic waveform reflected from the defect (scratch), and “Y” means the (surface) distance of the probe / defect during oblique flaw detection. “D” means the defect depth at the time of oblique flaw detection.
[0029]
On the menu 1 screen 61 displayed by the execution of steps S12 and S13, the "measurement" item, the "condition setting" 1 and 2 items, the "function setting" item, and the "function setting" The items of “evaluation software” are displayed in line units (line units). Condition setting 1 means the first page of the condition setting items, and condition setting 2 means the second page of the condition setting items. Each item of “measurement”, “condition setting”, “function setting”, and “evaluation software” is an essential item in setting related to measurement, and displays the title thereof. Actually, the setting items "Measurement", "Condition setting", "Function setting", and "Evaluation software" have ranks, and "Measurement" and "Condition setting" are setting items for beginners. , “Function setting” is a setting item for intermediate users, and “Evaluation software” is a setting item for advanced users. In an actual display screen, the color is preferably displayed for each setting item in accordance with the degree of importance, so that the color can be easily identified. For example, yellow is used for setting items for beginners, red is used for setting items for intermediate users, purple is used for setting items for advanced users, and blue is used for beginners.
[0030]
On the menu 1 screen 61, the contents of essential items such as measurement items and condition setting 1 and condition setting 2 with high importance are displayed in detail on the right side and are enlarged. On the other hand, in the menu 1 screen 61, the items of the function setting and the items of the evaluation software are indispensable items having a low importance corresponding to a measurer with a high level of skill, so that only the title display is used, It is a reduced display. As described above, in the menu 1 screen 61 which is the initial setting screen, essential setting items for beginners, which are highly important, are arranged in advance in the upper position and displayed as detailed enlarged display, and are displayed for intermediate and advanced users. The setting items of low importance are located at the bottom and are displayed as a simplified reduced display.
[0031]
According to the above configuration, since the entire menu contents are visible and displayed in different colors, the visibility of the menu screen is improved, and the menu content selection operation is facilitated. In particular, for beginners, essential setting items with high importance are displayed in detail enlarged from the beginning, so that setting can be easily performed. What is necessary is just to set about the item displayed in detail enlarged.

Next, an operation of moving the line cursor 65 and selecting another item will be described. In determination step S15, it is determined whether or not clear key 22b has been pressed. If the clear key 22b is not pressed in the determination step S15 (NO), the process proceeds to the determination step S16. In determination step S16, it is determined whether or not set key 22c has been pressed. If the set key 22c has not been pressed (NO), the flow proceeds to the judgment step S17. In the determination step S17, it is determined whether or not the f1 function key 22a has been pressed thereafter. When the f1 function key 22a is pressed once, the above-described line cursor 65 moves downward by one line. In the flowchart, this operation is determined by determining whether or not the position of the line cursor 65 is at the bottom at the determination step S18 when YES is determined at the determination step S17, and when the position is not at the bottom (NO) when determined at the determination step S18. The line cursor 65 is moved down one step (step S20). Thereafter, the processing flow returns to the determination step S15. If the line cursor 65 is at the lowermost position on the menu 1 screen 61 shown in FIG. 7 (YES) in the judgment step S18, the line cursor 65 is moved to the uppermost position (step S19). The subsequent processing flow also returns to the determination step S15. If both determination steps S15 and S16 are NO, and if the determination step S17 is YES, that is, if the f1 function key 22a is pressed, the line cursor 65 moves downward each time. And when it reaches the bottom, it moves to the top. Therefore, the f1 function key 22a is used as an operation key when selecting a line on the menu 1 screen 61. By operating the f1 function key 22a, the measurer can align the line cursor 65 with the line of the item to be set.
[0034]
In the loop of the above processing flow, when the line cursor 65 is aligned with the line of the desired setting item on the menu 1 screen 61, the setting item can be selected by pressing the set key 22c. At this time, the determination in step S16 is YES, and the processing flow proceeds to determination step S21. In determination step S21, it is determined whether or not there is a lower layer (another page portion). If YES, the selected setting item is opened together with the lower layer, a detailed enlarged display is performed on the upper line, and a detailed enlarged display is displayed on the upper line. The displayed setting item is closed and is displayed in the lower part in a simplified reduced display (step S22). Thus, a new menu screen (setting screen) is displayed on the display unit 21. At this time, on the new menu screen, the line cursor 65 is arranged on the uppermost line (step S23). After that, the processing flow moves to the judgment step S17. If the determination in step S21 is NO, the process proceeds to step S24. In step S24, the screen returns to the basic screen 51, and the contents of the line of the setting item where the line cursor 65 is located are displayed in the function menu (area 51b) at the bottom of the basic screen 51.

For example, the “edge echo method” is a method of evaluating the size of a crack using an echo reflected from the edge of a crack (crack defect). The “distance correction method” is a method of evaluating the size of a flaw from the height of a reflected waveform.
[0040]
The line cursor 65 is displayed on the menu 3 screen 63 and the menu 4 screen 64 in the same manner, and the positioning and the selection operation can be performed as in the case of the menu 1 screen 61. On the menu 3 screen 63 and the menu 4 screen 64, the item of “measurement” is held in the state of the detailed enlarged display at the second position from the top.
[0041]
According to the configuration of the menu screen (setting screen), the entire menu contents can be overlooked on the menu 1 screen 61, which is the basic setting screen, and the line cursor contributing to the selection operation is set for each line of each setting item. And the movement is cyclic. The menu contents of the menu screen have a tree structure and a cyclic structure. In addition, the entire contents can be viewed on any of the selected menu screens. Further, all of the setting items selected by the line cursor 65, including the contents located therebelow, are constructed in a hierarchical structure, and all the contents are displayed on the menu screen by the selection operation.
[0042]
In the flowchart shown in FIG. 4, if the clear key 22b is pressed in a state where the menu 1 screen 61 is displayed on the display unit 21, YES is determined in the judgment step S15, and the process returns to the basic screen 51 (step S25) and ends. I do. At this time, on the basic screen 51, the original menu line is displayed in the function menu (area 51b). If it is determined in step S17 that the f1 function key 22a has not been pressed and the answer is NO, the process proceeds to step S26, where it is determined whether another function key has been pressed. When YES is determined in the determination step S26, the process returns to the basic screen 51, and the content of the line of the setting item where the line cursor 65 is located is displayed in a function menu (area 51b) at a lower portion of the basic screen 51 (step S27). Move to the parameter setting menu (step S28). If the determination in step S26 is NO, the process returns to step S15.
[0043]
Next, the parameter setting menu will be described with reference to the flowchart of FIG. When the basic screen 51 is displayed, a parameter setting menu is displayed in the area 51c. The measurer operates one of the function keys. In the processing flow of the MPU 31, in step S31, the number of the pressed function key is checked. As a result, the parameter of the item corresponding to the pressed function key is displayed on the parameter setting menu (step S32). The next determination step S33 is a process of determining whether or not to determine a numerical value based on the operation state of the set key 22c, and a determination step S34 is to determine whether or not to return the numerical value to the original state with the operation state of the clear key 22b. Processing. When NO is determined in the judgment steps S33 and S34, a numerical value is set in a judgment step S35. The setting of the numerical values of the parameters is performed by operating the above-described four operation keys (number setting keys) 22d. If it is determined that the operation key 22d has been operated (YES), the numerical value of the parameter is changed (step S36). During the setting of the numerical value, the loop of steps S33 to S36 is repeated. If the result of the determination in step S33 is YES as a result of operating the set key 22c, the numerical value is determined (step S37). When the result of the operation of the clear key 22b is YES in the judgment step S34, the numerical value is returned to the original value (step S38). In both cases of steps S37 and S38, the parameter setting menu is thereafter erased (step S39). If the operation key 22d is not operated in the judgment step S35 and the answer is NO, it is judged in the judgment step S40 whether or not the function key is operated. If the same state is maintained, the parameter cursor is moved to a predetermined state (step S41), and the process returns to step S33. If there is no operation of another function key, the process directly returns to step S33. On the other hand, when the function key is operated, it is determined whether or not the key is the f1 function key (judgment step S42). If YES, a menu list is displayed (step S43). A setting menu is displayed (step S44), and thereafter, the process returns to step S33.
