The fabric strength tester is an instrument used to measure the tensile strength and breaking strength of fabrics. Before taking measurements, you need to pay attention to the following matters to ensure the accuracy of the test results and the long-term use of the instrument:

1. Instrument calibration: Fabric strength testers need to be calibrated regularly to ensure accurate test results. The instrument should be calibrated before each use and the manufacturer's recommendations should be followed.

2. Sample preparation: Sample preparation has a great influence on the test results. You should ensure that the sample size, shape, and thickness meet the instrument requirements and are free from damage or defects. Before testing, the sample should be stretched to eliminate any instability.

3. Operating procedures: Operation should be carried out in accordance with the operating manual provided by the manufacturer. It should be noted that the position of the sample clamped on the test clamp should correspond to the indicator mark on the clamp. It is necessary to properly control the force when clamping the sample to avoid overstretching or damaging the sample.

4. Test parameters: Test parameters should be selected based on the application and standard requirements. This includes test speed, clamp gap, loading method and number of tests. When conducting multiple sets of tests, test parameters should be carefully recorded for comparative analysis.

5. Data processing: Appropriate data processing of test results is required. This includes measuring and recording the sample’s breaking force values, elastic modulus, elongation and other parameters, and calculating the average and standard deviation. Factors such as sample size, shape, and thickness need to be considered when performing data analysis.

6. Maintenance: The fabric strength tester is a precision instrument and requires regular maintenance. This includes cleaning test jaws, checking components such as sensors and control circuits for integrity, and replacing damaged parts.

7. Safe operation: Safety issues should be paid attention to when using the fabric strength tester. Wear appropriate personal protective equipment such as gloves and goggles during testing and avoid placing hands or other body parts near the test clamp.

In short, using a fabric strength tester requires following strict operating procedures and precautions to ensure the accuracy of test results, long-term stability of the instrument, and safe operation. Before purchasing a fabric strength tester, you should consider the application and testing requirements to select the appropriate instrument model and specifications. Always refer to the equipment's operating manual and relevant standards, and follow the manufacturer's recommendations and guidance.
