SOFTWARE ซอฟแวร์

Function of software

1. Switch on the instrument and exceed zero

After switch on the instrument, firstly, switch on the power of external device and then the turn on the computer. Thus the

software begins to work, firstly appears the icon of our company and the cover of software, automatically hidden for a few

moment.

2. Main display window

If want to go into “ main display window”, you may select the item “main display window”. The reading value is displayed

by big character above the screen: there are two line simulating scales and the upper line is coarse scale. The range is 0.20

and every unit is 0.0022. The marked figure is accordance with the current display value and the black part is the cursor. The

place that the cursor is located is the current display figure, which is moved right and left along the change of the figure.

When the cursor reaches the limit, the scale value adds or reduces a block and the cursor goes into from the other side again.

The lower line is fine scale with range of 0.020 and every unit of 0.0002. The movement is same as the coarse scale. You

will find out in later, it is convenient to find “reversal point” using this simulating scale. If the measuring axis does not

exceed zero, on the upper side of big character will display: “Now are waiting for zero or not, please press zero button”. For

high accuracy measurement. It must exceed zero and then be on other operations.

Pressing the button “zero”, the reading value is zero. The read value can be sampled, saved and calculated by pressing the

left or right mouse. When you find that the sample value is wrong, strike the button “Esc” to cancel the current the point.

Pressing the related button can convert the Metric and Inch. Pushing button “Esc” can return to main menu and select

required function.

3. Input data by keyboard

If you need to input data through keyboard, strike the icon “keyboard input” and then appears the dialog box. Input relative

data by the prompts and then press the button OK to display the current inputted data in the list. Press the button “cancel

input” to cancel the current inputted data. At last, press the button “Esc” to finish input and return to main menu. The input

coordinate can be on all kinds of calculations.

4. Display current all coordinate points

If need to display or print current collected points, striking the “display coordinate” with the mouse is Ok.

5. Save current sampled point

For save the current sampling point for long, it appears the dialog box . when striking the icon “save coordinate point”.

The screen appears the hints that select path and input file name, then press the button “save” to ends. For example, to save

the sampling point into your disk, set the file name as ShuJu, then select the path to enter the ShuJu and press the button

“save”, thus the point is saved in the file of ShuJu. If the process has error, it will display error information.

6. Extract saved sampling points

if desire to extract the saved coordinate, strike the icon “extract coordinate”

7. Modify sampling point by keyboard

If find some coordinated that are wrong and need to correct, strike the icon “keyboard modify” by the mouse and then

appear the Fig.6.

You need to modify the sampled data, input the number of the point according to the prompts. Then enter correct value

and press the button “OK”.

8. Delete sample points

To delete some tedious and useless points, strike the icon “ delete coordinate” through the mouse and appear the dialog box

as the Fig.7. There are following options: delete single point, delete a series continuous points (many series continuous

points) and delete all sample points, now description as follows:

9. Delete single point

If you want to delete one point, strike the first item in the figure 7, and this time the number selected will turn into bright

from dark. Then choose the number in the bright place and press the button “OK” , thus can delete the point. For example,

want to delete the fifth point, at first, make the selected serial number be bright and select the number 50, then press the

button “OK”.

10. Delete a group continuous points

The operation method is same as the above, strike the second item in the figure 7 by the mouse to make the number be

bright. According to the prompts, select the number to be delete and press the button “OK” to delete a group points. For

example, to delete the points from 5 to 15 of 30 points, only need to input the number 5 in the first prompt and number 15 in

the second prompt. And then press the button “OK” to delete these points.(Repeating the operation, many groups continuous

points can be deleted.). The rest sample points will be anew arranged. See the fig.8.

11. Delete all points

To delete all sample points, strike the third item in the figure 7 using the mouse and press the button “OK” to delete all

points. Press the button “Esc” to cancel current operation.

12. Select display value

For the software can provide different gratings, it has the function of select the display value. We have adjusted the function

before leaving factory, so user does not change it unless the model of main machine is changed. The method is: select the

“select display value” of “rectify value” or strike the icon “select value”, then appear the dialog box as shown in the Fig.9.

Select the options with mouse and then press “OK”.

13. Set new rectifying value

The software can rectify the value error of the instrument. For the software is provided with the instrument, the rectify value

has already been saved in it and the user does not change it unless the big error tested by inspecting department exists. The

method is: select the “select display value” of “rectify value” or strike the icon “select value”, then appear the dialog box as

shown in the Fig.10. The figure 10 shows the total rectifying values, which is rectifying value of error of the instrument. The

gauge block can test the error. The tested points is a discrete point with space of 10 mm, and the starting points is located in

the limit position of starting points of effective absolute range of the instrument. To modify the total rectifying value, input

the new value again and press the button “OK”. User can enter the error value, “+” means bigger than the real value and

“-“ is smaller than the real value. The software adopts the “superadding way”, that is, the user only can input the adding

value with the keyboard. When some point need not add, it should input the “0”. Once saved, the new data cover the old

data.

Although input the discrete point, any length has the rectifying function for the software adopts math processing. User can

zero in any position, the result is not changed.

 14. Rectify the temperature

The screen appears the dialog box as the Fig. 11 when select the “rectify temperature” of “rectify value” or strike the icon

“rectify temperature”.

To modify the current temperature, user can input the new value in the dialog box. Where: 10.0e-6 means 10.0×10-6. Press

the button “OK” to modify the temperature and “Esc” to cancel the operation.

15. Find “reversal point”

For horizontal length instrument, it is common and base operation to find “reversal point”. After the instrument has the

digital display function, it provides many strongpoints, but it is not convenient to find “reversal point” than the traditional

instrument. The software uses the multi-function of computer to be on aided operation, it is easy for finding “ reversal

point”.

15.1 Find the “reversal point” with simulation method

The scale under the screen is the simulating scale of traditional optical instrument. The color block expands towards right, it

means the size is increasing, vice versa. When find “reversal point”, first look the coarse scale and then fine scale to

determine the fine position.

15.2 Automatically find the “reversal point”

16. Measuring smooth workpiece

The measuring principle of measuring smooth workpiece. According to the hints under the screen, you may select required

function and strike the relative icon with the mouse.

16.1 External direct measurement

After select the function, the screen is shown in Fig.13.

Firstly, user should check the parameters whether is same as your desire, then quit the page after modifying it. If have not

sample the data, press the button “OK” to enter into displaying state, thus can measure, sample data. If need automatically

find reversal point, select the item “finding reversal point”. After collecting the data in sequence, press the button “Quit” to

display the result. If need to print the result, press the icon “printing result”.
