Principle
The testing machine adopts a fully digital speed control system with high speed regulation accuracy and stable performance and a stepper motor as the driving system. The controller is the core of the Control system. The screen display of test force, peak test force, beam displacement, test deformation and test Linear dispersion is realized through the control and data processing software of the Windows Operating interface. All test operations are automatically completed on the computer through the mouse.
Applications
Spring performance parameter testing, resilience sample testing, industrial and mining enterprises, technical supervision, commodity inspection and arbitration, scientific research institutes, Universities & colleges, Quality control units
Standards
JB/T7796-2017, national standards, ISO, JIS, ASTM, DIN
Steps
1. Start the test software on the computer with the mouse
2. Set test parameters, including force value units, displacement units, Graduation, test mode, etc
3. Select the test mode: fixed height force measurement value, fixed deformation force measurement value, fixed force value to measure height or fixed force value to measure deformation
4. Start the test, Test speed and program change automatically
5. Dynamic display of data and Linear dispersion during the test
6. After the test is completed, the moving beam is automatically reset to its original position
7. Test data and Linear dispersion are automatically stored and can be queried or exported
8. Make qualified judgments according to preset criteria
9. Prepare and print test reports
Notice
* Power supply voltage AC 220V 50HZ
* Pay attention to the overload protection function to avoid overload use
Use emergency shutdown devices in emergencies
Regularly check the leakage protection device
Verify that the displacement and force values are set correctly before the test
* Test space Effective Travel is 430mm, do not exceed the limit
* Keep equipment clean to avoid affecting Measurement accuracy
