What should be noted for the accuracy of arc resistance tester testing
Date: 2025-08-04Read: 2
The accuracy of the LDH-15KV arc resistance tester should pay attention to the following points：
Equipment calibration and maintenance Electrode status Regularly clean or replace worn electrodes (such as tungsten electrodes) to ensure precise electrode spacing (e.g. 6.35 ± 0.1mm) and avoid electrode erosion affecting discharge stability. High voltage system calibration Calibrate the voltage output every six months, with an error controlled within ± 2%, and equip a voltage regulator to ensure stable input voltage. Gas system Control the gas flow rate (usually 10L/min) and purity, check the sealing of the pipeline to prevent gas leakage from affecting the test results. Sample preparation and installation Size and processing Process samples according to standards (such as a diameter of 50mm and a thickness of 3mm), polish the surface and clean it with anhydrous ethanol, and pre treat for 24 hours (under conditions of 23 ± 2 ℃ and 50 ± 5% humidity). Installation specifications Fix the sample with a fixture to ensure that it is perpendicular and in close contact with the electrode, avoiding testing errors caused by poor contact. Parameter Setting and Operating Standards parameter matching Adjust the voltage (10-15kV) and current (such as 10/20/40mA) according to the material characteristics. The new material needs to optimize the parameter combination through pre testing. environmental control Maintain the humidity of the testing environment between 40-60% to avoid contamination of the sample surface by oil or dust. Operational Security Wear protective equipment during operation, close the test chamber door, and avoid contact with high-voltage parts. Data recording and maintenance real-time monitoring Record the failure time of the sample (such as carbonization or combustion), use the system to automatically collect data, and ensure the accuracy of the data. regular maintenance After every 50 tests, check the electrode status, clean the carbide residue, and calibrate the equipment.
By strictly following the above precautions, the testing accuracy of the arc resistance tester can be effectively improved, ensuring the reliability and consistency of the test results.
