The low voltage resistance of the wiring harness comprehensive tester is insufficient

Jan 17,2024

1. Wire quality issues
Low voltage resistance testing may be affected by wire quality. If there are problems such as poor welding, breakage, or substandard material quality in the manufacturing process of wires, it can lead to an increase in low-voltage resistance. At this point, visual inspection and testing of the wires are required to confirm if there are any issues. If there are any issues, the wires need to be remanufactured or replaced.
2. Damaged insulation layer
The insulation layer of the connecting wire may be physically damaged or chemically corroded during use, resulting in an increase in the resistance of the insulation layer. In this case, it is necessary to check the integrity of the insulation layer and repair or replace the damaged parts. At the same time, take preventive measures to ensure that the connecting wires are no longer damaged.
3. Joint connection issues
The joints of the connecting wires are prone to problems. If the joints are poorly connected or corroded, it can lead to an increase in low-voltage resistance. Therefore, it is necessary to check the connectors of the connecting wires to ensure that they are clean, securely fastened, and free from oxidation or corrosion. Clean and maintain as necessary.
4. Temperature and humidity effects
Temperature and humidity may also have an impact on the results of low-voltage resistance tests. The temperature and humidity of the testing environment should be within the standard range to ensure accurate test results. If the environmental conditions do not meet the standards, it may be necessary to adjust the testing conditions or perform calibration.
5. Testing equipment issues
Finally, the results of low-voltage resistance testing are also affected by the quality and accuracy of the testing equipment itself. Ensure that the testing equipment is in good condition and undergo regular calibration and maintenance to ensure the reliability of the test results.
Based on the above reasons, when the wiring harness comprehensive tester shows that the low voltage resistance is not satisfactory, it is necessary to carefully inspect factors such as wire quality, insulation layer integrity, joint connection, testing environment, and testing equipment to identify the root cause of the problem. Once the issue is confirmed, appropriate measures should be taken to repair it and ensure that the quality and performance of the connecting wires meet the requirements.
Through regular maintenance and quality control, the risk of low voltage resistance failure can be reduced, the reliability of the connection line can be improved, and the connection line can be ensured to work normally in various applications, providing stable electrical signal transmission and power transmission for various industries. This helps to improve production efficiency and product quality, reduce failure rates, and ultimately bring greater economic benefits.
