4. Main Unit Feature:
4.1 Adopt floor structure,High Stiffness, lower for tensile, upper for compression,upper for tensile, lower for compression, double space. The beam is step less lifting.
4.2 Adopting ball screw drive, realize no clearance transmission,make sure the precision control of the test force and deformation speed.
4.3 The shiel plate with limit mechanism used to control the beam moving range, in order to avoid sensor damaged due to the moving distance is too large.
4.4 The table, moving beams is made of high quality precision machining steel plate , not only reduce the vibration generated by specimen fracture, but also improve the stiffness.
4.5 Three columns of mandatory orientation, make the main unit rigidity much improved, to further ensure the repeatability of measurement.
4.6 Adopt bolt type grip installation, make the grip replace easier.
4.7 Adopt AC servo driver and AC servo motor, with stable performance,more reliable. Have over-current, over-voltage, over speed, overload protection device.
5. Software Function
5.1 Defined function: according to different types of users, different material properties, different test standards, different languages, flexible setting the test program to meet the test requirements.
5.2 Input Function: Entry specimen parameters before the test, you can single input sample parameter, you can also batch input sample parameters, you can modify the sample parameters before the test, the specimen parameters can be modified after the test, fully satisfy your operating habits.
5.3 Data processing query functions: fully equipped data query function, print function, the export function to ensure the accuracy of the test data, reliability, real embody and reflect the nature and characteristics of the material test data.
5.4 Curve analysis function: All the material properties can be reflected by the data curve, so the powerful data curve analysis function can help you better mastery and understanding of the material test properties, which is your best helper to analyze the material.
6.Software Feature:
6.1 Auto zero clearing : when test begin to start, the system auto zero clearing.
6.2 Auto calibration:system can automatically realize the value accuracy of the calibration.
6.3 Auto return:finish test, the cross beam will auto return to the starting position.
6.4 Auto gear shifting (when choose classify gear test): According to the load size automatically switch to the appropriate range, to ensure the accuracy of the test data.
6.5 Auto speed changing:The cross beam moving speed can auto chang during the test process according to the preset program, also can manual change.
6.6 Auto saving: adopting the the database management way, the test data and curve automatically saved after the test.
6.7 Auto calculating:when finish test, automatic calculate elastic modulus, yield strength and the percentage elongation stress, etc ( Different test method, different analysis date.) , can auto analyze, also be artificial correction analysis results, improve the accuracy of the analysis.
6.8 Display way: Dynamic display of data and curves with the testing process.
6.9Result comparison: Multiple test curve can use different color superposition, reproduced, enlarge , presenting comparison of a set of sample.
6.10Curve choice:can choose Stress - strain, force - displacement, force - time, displacement - time, and other curves to display and print; Can switch at any time to observe, zoom in and zoom out, horizontal or vertical movement, real-time high speed sampling.
6.11 Test standard: Integrated with about 40 kinds of national standard or test method, can meet the various test need of customers.
6.12 Test report: According to user required format to compile reports and can print bulk data.
6.13 Limit protection: with mechanical and Programmable two level limit protection function.
6.14Overload protection: when the load exceeds the maximum file of 3-5%, automatic stop.
6.15 Other protection:with overload, over current, over voltage,displacement of the upper and lower limit and emergency stop protection function .
