Počítačová kalibrace napínacího stroje, počítačový software tension machine calibration, tahová zkouška machine calibration interface power sensor, cestovní senzor, rubber extenometer, metal extenometer and system Settings five TAB, select each TAB for the corresponding sensor calibration or setting.

1. Calibrate the force sensor

Select the force sensor TAB, as shown in Figure 6.There are four force sensor channels shown on the left: “50kg”, “0.0kg”, “0.0kg” a “0.0kg”.

The calibration process is as follows:

1. Plug in the force sensor to be calibrated, such as the force sensor with a range of 50kg, and select a force sensor channel on the left;

2. Input the range of the sensor in the “rozsah” input box, jako “50” kg;

3. Input the zero-value force of the sensor in the zero-value input box, and generally input “0”;

4. Click the “Empty” button to empty the calibration table;

5. Calibration point 1: empty the sensor, return the force to zero, and input “0” kg in the input box to the right of the “standard weight value”. Then click the “Take point” knoflík, then the AD value and the standard weight value of point 1 will be taken into the calibration table;

6. Calibration point 2: Load the sensor with a certain value of load, such as hanging 5kg weights, input the load value of “5” kg in the input box on the right of “standard weight value”, and click the “take point” knoflík, then the AD value and standard weight value of point 2 will be taken into the calibration table;

7. Calibration point 3: The method is the same as point 2. If the calibration point 3 is continued, a “AD value” a “standard weight value” can only be larger than point 2, otherwise the calibration will be inaccurate;

8. Calibration point 4: The method is the same as point 2. If the calibration point 4 is continued, a “AD value” a “standard weight value” can only be larger than point 3, otherwise the calibration will be inaccurate;

9. Calibrate point 5: The method is the same as point 2. If the fifth point is continued to be calibrated, a “AD value” a “standard weight value” can only be larger than point 4, otherwise the calibration will be inaccurate;

10. Calibration point 6: The method is the same as point 2. If the calibration point 6 is continued, a “AD value” a “standard weight value” can only be larger than point 5, otherwise the calibration will be inaccurate;

11. Click the button “Write calibration data to acquisition Card”. If “write successfully” is prompted, then the calibration of a force sensor will be completed.

12. If the second force sensor is needed, repeat steps 1-11 above; otherwise, set the range of all other sensors to 0, and then click the button “Write calibration data to acquisition Card”.

Poznámka: at least 2 points should be calibrated. Steps 7~10 May not be performed.According to the characteristics of most sensors in China at present, a 3-point calibration can generally achieve very good accuracy. The second point generally values 3-5% of the sensor range, and the third point generally values 30-50% of the sensor range.If more than 3 points (počítaje v to 3 points) are calibrated, a “AD value” a “standard weight value” of the latter point must be greater than that of the previous point, otherwise the calibration will be inaccurate.If the AD value decreases as the standard weight increases, it can be increased by switching the two signal lines of the force sensor.When there is no load, a “AD value” is generally around 8400,000. When the sensor is loaded, a “AD value” changes in proportion. If the “AD value” is unchanged when the sensor is loaded, it indicates that the hardware is not working normally, which may be due to the damage of the force sensor or the failure of the acquisition card.

If found after calibration measuring force value has small difference with standard weight, can be addressed by calibrated once again, also can be directly modified by calibration standard weight values in the table data, such as software measurement is bigger than standard weight value, the calibration can be in the table 2 points of standard weight value in a bit, then click “to write the calibration data into the acquisition card” knoflík, reset again, until the two values are equal.

2. Calibrate the travel sensor

1. The input box on the right side of the “journey” coefficient input coefficient value, travel coefficient refers to the acquisition card each received 1000 odpovídající cestovní hodnotu, pulsní akviziční karta do 4 krát frekvence čísla řádku kodéru, jako číslo řádku kodéru je n, stoupání šroubu Lmm odpovídající koeficient plánu pro L/n / 4 * 1000, pokud není, vymažte číslo vedení kodéru nebo vedení šroubu, mohou být libovolné vstupní a testovací hodnoty jako např “1”;

2. Click the button “Zapište kalibrační data do akviziční karty”, a napište hodnotu “Cestovní faktor” do akviziční karty;

3. Click the “Výlet do nuly” tlačítko pro resetování “aktuální výlet” na nulu;

4. Click the “nahoru” nebo “dolů” tlačítko pro ujetí určité vzdálenosti od stroje, a změřte vzdálenost posuvným měřítkem;

5. Zkontrolujte, zda hodnota “aktuální cestování” se rovná naměřené hodnotě. Pokud je hodnota “aktuální cestování” je větší než naměřená hodnota, prosím změňte hodnotu “Cestovní koeficient” na menší hodnotu; otherwise, změňte hodnotu na větší, and then click the button “Write calibration data to the Acquisition Card” to write the new value of “Cestovní koeficient” to the acquisition card;

6. Repeat steps 3-5 until the “current stroke” value equals the measured value;

7. Complete the calibration of the travel sensor;

3. Calibrate the rubber extenometer

If the machine is connected with a rubber extensometer (also known as large deformation), the rubber extensometer needs to be calibrated. Before calibration, please be sure to set “user parameters” -& GT;“Control parameters” -& GT;The “přemístění” under “sensor” is selected as “rubber extenometer”, otherwise the calibration of rubber extenometer cannot be carried out.The calibration interface of rubber extensometer is shown in Figure 8:

4. Calibrate the metal extender

If the machine is connected with a metal extender, it is necessary to calibrate the metal extender. Before calibration, please make sure to set “user parameters” -& GT;“Control parameters” -& GT;The “přemístění” under “sensor” is selected as “metal extensometer”, otherwise the calibration of metal extensometer cannot be carried out.The calibration interface of metal extensometer is shown in FIG. 9:

The calibration process of the metal extensometer is the same as that of the force sensor.
