ETT-AM Electronic Tension Machine Operating Procedures!

The correct use of the tension machine can not only extend the use time of the instrument, but more importantly, the experimental results can be more accurate, the following by Baili Bio to introduce the operation procedures of
the tension machine 。 ETT-AM electronic tensile testing machine tensile machine operating procedures: First, the tensile machine use environment 1.
On a solid foundation or work table, correct installation, no vibration in the environment, no corrosive medium; 2.
The fluctuation range of the power supply voltage should not exceed 10% of the rated voltage, the power supply of the testing machine should have reliable grounding, and the fluctuation of the frequency should not exceed 2% of the rated frequency; .
3.
Room temperature 10 °C-35 °C, relative humidity is not more than 80%.

Second, the operation step of the tensile machine 1.
Make a sample: make a sample according to the requirements of the test standard, and measure its size and other data
.
2.
Power on: first open the software measurement and control system on the computer, and then open the power supply
of the testing machine.
Select the appropriate type
of test based on the test you want to perform.
3.
Trial operation: Select the appropriate speed to make the testing machine lift and lower to make sure that the tension machine is running normally
.
4.
New record: according to the number of tests to be conducted, the corresponding number of test records is created; And fill in the corresponding batch number, number, test environment, specimen size and other related data
.
5.
Loading and placing the specimen: adjust the position of the specimen on the testing machine and install and place the specimen
.
6.
Select the measuring range: according to the range of test force and deformation required for the test, adjust the tensile machine to the appropriate test force and deformation gear (range).

7.
Clearance: Clear the test force, deformation, and displacement to zero
.
8.
Test speed: according to the requirements of the test process in the standard, set the appropriate test speed; If there is no speed requirement on the standard, set a more appropriate speed, and the speed should not be too large, so as not to affect the test results
.
9.
End conditions: According to the requirements of the test process on the standard, if the specimen is destroyed (such as tensile and cement compression), select "breaking judgment"; If the pull (or pressure) ends with a certain test force, select "Target", "Test Force"; If you pull (or press) to a deformation and it ends, select Target, Deform
.
10.
Test start: Click the "Test Start" button to start the experiment
.
11.
End of test: After the test is completed, the "End of Test" button is automatically pressed
.
If you need to end the trial halfway, you can also manually end the trial by pressing the End of Trial
button.
12.
Test results: Click the "Analyze" button to view the corresponding test results
.
Continue experimenting: Click the "Experiment" button to return to the experiment operation interface, click "Next" button to switch the experiment record to the next one, repeat the 5-11 steps for the experiment
.
13.
Save data: If the test data needs to be saved, press the "Save" button to save the test data to the database for reference
.
Print Report: If the test results need to be printed, press the "Output Report" button to output the test results to a Word document and print
.
14.
Shut down: first turn off the power supply of the testing machine, and then turn off the software measurement and control system and the computer
.
Third, the tensile machine precautions 1.
Before the tensile machine works, check whether the reducer under the workbench has lubricating oil; 2.
The preload speed is less than the experimental speed, which prevents the two fixtures from touching so as not to damage the fixture; 3.
Carefully connect the line of the sensor; 4.
The lead screw and silk mother of the testing machine are added to the lubricating oil once and every six months; 5.
Keep the testing machine clean
.
Fourth, the common faults and treatment methods of the tensile machine; 1.
If the test force and displacement do not change during the test, check whether the tension machine connection and socket are good; 2.
If abnormal sound is found during the test, stop immediately to check the tension machine transmission system
