Calibration method and usage standards of electronic universal testing machine

The electronic universal testing machine can test rubber, plastic, leather, metal, nylon thread, fabric, paper and aviation, packaging, construction, vehicles, etc., and can conduct tensile tests, pressure tests, peel tests, tear tests, and shear tests. Today, the editor will tell you about the calibration methods and usage standards of electronic universal testing machines. Let’s take a look.

1. Calibration method of electronic universal testing machine

1. Items that need to be corrected: force value, stroke

2. Tools for calibration requirements: standardized weights, electronic stopwatches and standardized straight steel rulers

3. Calibration cycle: one year

4. Calibrate pace

(1) Unit conversion: 1kgf=9.80665 Newtons

(2) All data in the computer is controlled by the computer, and all data in the control panel is explicitly reduced to zero. Hang the standard weight quietly on the fixture, record and display the force value, and calculate the difference with the standard weight. The error should not exceed the regular error value of the universal test machine.

5. Test speed correction:

(1) Start the stopwatch of the test machine to be initially counted for one minute, the timing is aborted, and the test machine will be terminated by itself. According to the time of the stopwatch, record the fixture stroke value and the speed per minute (mm/min), observe the difference between the fixture stroke value and the straight steel ruler, adjust the speed setting, start the test machine again to measure the accurate value, and calculate the fixture stroke error value, which should not exceed the rules. Material testing machine calibration method;

(2) First record the position of the fixture under the test machine and set the calibration speed on the software. The fixture stroke is also measured using a standard straight steel ruler.

2. Standards for use of electronic universal testing machines

1. The host of this device adopts a floor-standing frame structure, which has the characteristics of high strength and small deformation, and the appearance is quite beautiful and generous.

2. Our company's electronic universal testing machine uses Taiwan ABBA's high-precision ball screw, so it has perfect stability.

3. The load sensor of the electronic universal testing machine is made of American products, which has the advantages of high measurement accuracy and minimizes errors.

4. The transmission part of the equipment adopts a synchronous transmission method of arc teeth, and a gapless bidirectional method can be performed during the transmission process.

6. The fixture of the electronic universal testing machine has been specially designed, very firm and very convenient to operate.

Mechanical equipment is essentially the same. Only by mastering the correct method can the entire experimental process be smoother and the experimental data are more accurate. The above is a related introduction to the calibration methods and usage standards of the electronic universal testing machine. I hope it can help you.
