Tensile Testing MachineDuring use, the accuracy of the test results decreases due to the aging of electronic components. Therefore, it is necessary to recalibrate the tensile testing machine from time to time to ensure the stability of the testing machine's testing accuracy and keep the testing machine at a high testing accuracy level.
The calibration of the tensile testing machine In general, it happens that the manufacturer sends people to calibrate directly. If the customer wants to calibrate the testing machine himself, he should know where the testing machine needs to be calibrated.The calibrationtion of the testing machine is generally aligned to the test force value of the testing machine and the moving beam travel speed up and down for calibration.
Try the force correction first
calibration tools : standard weight, standard load tester
Test method: Clear all the test data in the control program, slightly hang the standard weight on the fixture, record and display the force value, and calculate the difference with the standard weight. The error should not exceed the error value specified by the universal testing machine.
Second: Test machine train speed calibration
Calibration Tool: Standard Steel Ruler
Testing method: First pick up the moving beam of the testing machine Set the correction speed and timing time in the software control interface, start the testing machine until the testing machine stops running, measure the moving beam stroke with a steel ruler, calculate the difference between the theoretical speed and the actual running speed of the moving beam, and then calibrate. Then adjust the calibration speed and test again. Repeating the test several times can reduce the tensile speed error of the testing machine inadjusted within the specified error.
