How to check whether the stretch machine equipment is in good condition

Tensile testing machine is a precision mechanical testing equipment that can a small mistake will lead to the failure of the experiment. Many users report that after a while the tensile testing machine doesn't seem as effective as before. The experimenter will suspect if the experimental results are inaccurate and ask the manufacturer for repair. In fact, it is quite normal for a similar situation to occur. After a period of mechanical operation, the accuracy or mechanical operation must not be compared with the new machine. qrITextile Testing Instruments, Testing Equipment Manufacturer

Share the tensile testing machine Method for self-control of force value and speed:qrITextile Testing Instruments, Testing Equipment Manufacturer
1. Force value detection of the tensile testing machine, is it 5kn or 5kn?After the traction machine enters the computer program, open the calibration interface, press the test start, take a standard weight and slightly hang it on the upper bracket connecting seat, note the force value displayed by the computer, and calculate the difference from the standard weight should the error does not exceed ±0.5%. (This method only applies to the microcomputer controlled tractor) qrITextile Testing Instruments, Testing Equipment Manufacturer
2. For speed test of tensile testing machine, first note the initial position of the cross arm of the machine, and select the speed value on the control panel (Use a normal straight steel ruler to measure the stroke of the cross arm). Then start the machine, and at the same time, the electronic stopwatch will start counting for one minute, and when the stopwatch reaches the time, press the stop button of the machine according to the time of the stopwatch. qrITextile Testing Instruments, Testing Equipment Manufacturer
