This system is based on the Windows 7 operating system and combines configuration software with PLCs to collect and process data during the testing process, which is then saved. Data is non-editable and non-deletable, ensuring its persuasiveness. Test data is automatically saved on the computer and can be queried at any time based on test numbers or dates. Data extraction and printing are available. Below is a detailed introduction to the system's operation method.

Double-click the icon after the computer boots up normally.A password input dialog will pop up. Enter the password 935488, and click "OK." The data collection software will then enter the running state.

2. First, you'll enter the homepage window, where the software includes operation instructions that can be referenced alongside specific actions.

Click the operation instructions on this page.

A blue border is added to the button. Clicking any button will then display a pop-up with the button's function and settings instructions.

Click on other buttons, the previous instructions will automatically close. Click "Exit," and you can leave the view of instructions. At this point, you can normally switch windows and operate through the buttons. Let's go into the monitoring screen.

3. Preparations before testing, parameter settings.

Upon entering the monitoring window, a parameter setting prompt will appear. We've pre-set some commonly used parameters for direct access in the future.

The blue section, upon clicking, contains 5 preset groups that can be accessed at any time. The white section allows for direct text input. Considering that this section is not expected to be modified frequently.

Note that our bubble monitoring is set to the first option by default. Also, take note that the icons look different.

Before commencing the test, we can zero-calibrate the sensor to minimize measurement errors, select an appropriate range sensor based on the measurement requirements, and calibrate the sensor range.

Not calibrated, a prompt will appear. Once the relevant parameter settings are completed, you can proceed to the normal data collection testing process.

Some key parameters are not set correctly; corresponding prompts will be provided. Please check them during use.

4. Data Testing and Collection

First, click the water and gas switch, select the corresponding water pressure or air pressure, click to start testing, then select the test items, click the required test items with the mouse. The corresponding icon will turn red, indicating it has been selected. Set the corresponding parameters, allow for pressure drop, hold pressure time. The blue box in the image above is where the settings are needed. Click to continue testing, and the pump will automatically increase pressure. Once it reaches the set pressure, it will automatically stop and hold pressure. A pressure curve will appear in the right box, a straight line indicates no pressure drop, while a stepped decline indicates where there are leaks.

During testing, if an abnormality is detected and the test needs to be terminated, click "End Test" to interrupt the valve test. If the valve needs to be replaced with another part, click "Continue Test." Be sure not to click "End Test" or print the report, as this will result in the test data for the same valve not being saved in the corresponding box for that valve. For specific instructions, refer to the operation guide included in the software.

Table printing, after testing, click on "Table Print," and the printer will automatically print out the test data. Before printing, you can click on the test report to view the printout. After printing, the relevant data will also be saved into the system.

6. To retrieve stored data, when you need to locate stored data, enter the stored data window and search using the query number on the test report or a specific test time, then extract and generate a table.

After data extraction, click the preview and save table to view the extracted data in the table.

If a pressure curve during testing is required, click on "Curve Production," and the corresponding curve can be generated based on the saved data at that time.

7. Historical Curve Lookup: Real-time curves from past tests can also be viewed through the Historical Curve dialog box.

Click the red icon below to precisely locate pressure-time curves within a specific time frame by date.

If you have any confusion during the software usage, refer to the internal operation instructions as much as possible.
