Calculation Formula for Elongation of Wire

The formula for calculating elongation is f =(L2-L1) ÷ L1 x 100%. Elongation refers to the percentage ratio of the elongation of the original gauge length to the original gauge length of a specimen after tensile fracture. Elongation is an important parameter that represents the uniform or stable deformation of a material.

Operating Instructions and Precautions for Wire Elongation Tester

1. Fix the product to be tested onto the left and right fixtures of the wire elongation tester.

1.1 Firstly, the mobile fixture on the right end of the device should be at the standard distance position, with a distance of 250mm between the two fixtures.

1.2. Fix the left and right ends of the product with left and right fixtures respectively, and the product should be kept straight.

1.3. Wrap the screws on the sides of the left and right fixtures at both ends of the product a few times to prevent it from falling into the machine when removed.

2. Before testing, the reset button should be pressed to make the elongation meter display 0.

3. After completing all the above steps of debugging preparation, if there are no abnormalities, turn on the power switch and then turn the left and right switches to the right to start testing. If there are any abnormalities during testing, press the power switch to stop.

4. Record the test results in detail.

5. Test completed: ① Fix all screws of the testing instrument and check if the fixture is loose; ② Organize the test bench.

6. Attention:

6.1 Before the experiment, the first thing to check is whether the equipment has fixed the test product properly.

6.2 After all debugging preparations are ready, the equipment should be checked for smooth operation during testing.
