Torque wrench tester using method

The use of torque wrench tester, torque wrench tester to get the state to perform the correct operation, only the correct operation can be allowed to get the most accurate results. Torque wrench tester is a special device for testing torque wrenches and torque drivers. Our torque wrench tester is mainly used to test various fixed-force torque wrenches, digital display torque wrenches, preset torque wrenches, dial-type torque wrenches, Torque screwdrivers, screwdrivers, and various instruments and products that involve tightening forces.

How to Use the Torque Wrench Tester 1. Before using the torque wrench tester, check whether the power of the instrument is sufficient. If the power is insufficient, charge it first (can also be used when charging).

2. Place the quadrilateral probe of the test object into the square hole of the tester and use the handle at the other end of the test object above the height adjustment block (if the length is not enough, the whole loading device can be adjusted freely) .

3. Turn on the power switch and the displayed torque value is zero. If it is not zero, press the clear key to clear the torque value.

4, before the test, you need to set the upper and lower limit value, a very small storage value, a very small peak value, automatic peak time, automatic shutdown time, gravity acceleration and so on.

1. Upper limit value setting: The user sets the upper limit value and set it freely according to the need. The upper limit value is the automatic sound and light prompt. The upper limit value is not higher than the full scale.

2. Lower limit value setting: The user sets the lower limit value, and it can be set freely according to the need. The lower limit value is the automatic light prompt, and the lower limit value cannot be higher than the set upper limit value.

3. Very small storage value setting: The user sets a very small storage value according to the storage needs, and data smaller than this value will not be stored.

4. Very small peak hold value setting: According to the peak value, the user needs to set the automatic peak measurement freely, and the data less than this value is not saved by the peak value.

5. Automatic peak time setting: The user can freely set from 1 second to 99 seconds according to the time required for the peak value in the automatic peak measurement state.

6, automatic shutdown time setting: No operation, automatic shutdown time from 0 minutes to 9 minutes can be freely set (when set to 0 minutes, it means to lift the automatic shutdown).

7. Gravity acceleration setting: The user can set the gravity acceleration value according to the location of this area. The default is 9.794.

8. Restore the initial settings: If the user does not operate properly or changes the data several times, you can use this setting to restore the data from 1 to 7 to the factory state.

20 years time, snapping fingers. Looking back at the company's 20 years of hard work, it was tempting to have a lot of emotion. The 20-year enterprise development is actually a course of study management, thinking management, management management, and creation management. It is a process of continuous accumulation of management wisdom.
