    Why should choose the programmable withstand voltage tester?
    The withstand voltage tester is mainly used for the withstand voltage test of electronic products, household appliances, electronic medical equipment, LED lighting appliances, or electronic components, and can also be used for the dielectric withstand voltage test of any other insulating materials. The traditional (simulator) withstand voltage tester uses an autotransformer and a high-voltage transformer to perform manual step-up/step-down actions, and then cooperates with some simple hardware judgment and meter to make a withstand voltage tester, so it is Has several potential problems. LISUN LS9923 program-controlled withstand voltage tester not only improves the potential problems of the traditional withstand voltage tester, but also adds new research and development technology, and also adds new test functions to the product.
