Adopting TestExplorer measurement and control software, the
software is divided into four test modules: test, program, report
and measurement, and adopts guided operation process, which makes
test operation simple and easy.
The design concept of testing standards as the test base module,
including most of the current common test methods, support for
customized test program design, built-in hundreds of test results
and results expression calculator, greatly enriching the user's
personalized test needs.
* :: Powerful software features
TestExplorer measurement and control software for the analysis of
test results provides a variety of auxiliary means of analysis:
support for test curve playback, test results recalculation (add or
modify the calculation results); support for the results of the
unit switching and data modification; embedded data analysis and
comparison software to analyze the curve point by point and the
results; support for the analysis of the characteristic points, the
end of the test characteristics of the point in the test curve
automatically marked; with a variety of statistical functions to
automatically count and summarize the test results; test report
templating and customization, can be exported to Excel word pdf
report formats. With a variety of statistical functions, it can
automatically perform statistics and summarize the test results;
the test report is templated and customizable, and can be exported
to a variety of report formats, such as Excel, word, pdf, etc. It
adopts network technology to realize the diagnosis and upgrading,
and can be updated and upgraded online at any time free of charge
over the network.
At the same time, the software is also designed with a test process
editor, which can realize a variety of control modes, such as
stress rate, strain rate, displacement speed, constant load and
constant strain, multi-stage test process control, and seamless
switching between controls. In addition, the software has a
practical return-to-zero function, which can reasonably and
effectively eliminate the initial stress of the specimen by
adjusting the position of the crossbeam, thus obtaining more
accurate test results;
The software provides a variety of curve forms such as
stress-strain, load-displacement, strain-time, displacement-time,
etc. It can realize the functions of arbitrary coordinate system
configuration and display unit switching. Any curve can be selected
for comparison. And it provides printout of any size and curve
enlargement function, which can be realized by dragging the mouse
in the area to enlarge and pan the curve.
Finally, the software also has Chinese, English, Russian and other
multi-language support, to achieve the internationalization of the
software; support for customizing the display of real-time data
channel content and display unit settings;
High and low temperature chambers:
* High and low temperature box with RS485 or RS232 communication

chamber protrudes and can be nested in the test machine. The rear
part is designed according to the space requirement of
refrigeration and electrical system arrangement. (The rear
structure of the test chamber is on wheels at all four corners, and
the depth may be increased according to the arrangement of the
center of gravity.)
