Software Function Introduction

      1. Software Introduction

l Based on the WINDOWS operating platform, the software features simple operation, powerful functions, and a human-machine interactive structure. It adopts a standard Windows XP style, making it easy to learn and operate.

l The software uses a modular design. Modules for creating different test types, test control, and data analysis are independent and separated from the main program, enabling adaptation to test control and data processing for various test types.

l Test data can be added by users without quantity limits. New test records are created using templates, which is convenient and efficient.

l It automatically completes the test process, judges specimen fracture, and automatically records and saves test data. All test data are saved in the internationally universal XML format.

l It has efficient test data management functions, enabling quick query, loading, and deletion of test data in multiple ways.

l After the test, the system automatically analyzes and statistically processes the test results, and the analysis method can be set by the user.

l It has a flexible report editing function, providing users with a dedicated report editing tool for graphic layout, which is easy to learn and allows convenient printing of test curves, related images, and text.

l Users can delete test data as needed.

l Users can change the analysis method as required, and data rounding methods can be modified according to their own needs.

l Equipped with a dedicated database management module.

l Displays test force values in four digital ranges, with an accuracy of ±1% of the indicated value starting from 20% of each range.

l Displays deformation in four digital ranges, with an accuracy of ±0.5% starting from 20% of each range.

l Simultaneously records force-time, deformation-time, and force-deformation test curves. These curves can be switched for observation at any time, zoomed in/out arbitrarily, moved horizontally or vertically, and sampled at high speed in real time.

l Uses a human-machine interactive method to analyze and calculate the mechanical performance indicators of the tested materials. At the end of the test, the system automatically calculates elastic modulus, yield strength, tensile strength, etc. On the basis of automatic analysis, manual intervention can also be used to correct analysis results, improving analysis accuracy.

l Provides multiple report printing interfaces, allowing users to edit reports in any format as needed.

l Test data is managed using a standard database, which automatically saves all test data and curves.

5. Data Query Window

Historical test data can be queried in the database here. Simply input certain criteria, and the test data can be found immediately.

6. Automatic Calibration Window

Force values and deformation can be automatically calibrated. After our debugging is completed, if the user feels that the indicated value is inaccurate or the measurement and control parameters have been modified, they only need to click the automatic correction button, and the system parameters will be restored to the state during debugging.

7. The zero adjustment of the system adopts a digital design

Zero adjustment for the two acquisition channels can be done simply with mouse operations. Generally, the system only requires one zero adjustment. Under normal usage conditions, the system will automatically return to the true zero point.

8. Batch Data Processing and Batch Report Printing Window

Here, you can conduct summary analysis on a batch of similar test pieces, compare the measurement and control data, calculate the average value, and print the batch summary of the test pieces. We can customize special test reports for customers. These are just a few representatives of various forms. Test reports can also be edited and printed according to user requirements and are equipped with relevant processing software (batch processing, control programmer, MaxDoc report processor, MaxXls report processor, etc.).
