The Digital Manual Device of the DX Series are convenient to use due to its specifically structured coils and electrical machines. The DS integrates 2 tests, impulse/surge, and DC high-potential. It comes with a leakage current calculations and insulation resistance. The test results and wave forms can be stocked in the memory of the testers. They can be instantly printed using a traditional printer or moved to a computer. The surge test is done using the latest IGBT technology.的DX系列數字手動置使用方便由于其特殊結構的線圈和電機。DS成2測沖/浪涌直流電位。它備了一個泄漏電流和絕緣電的算。結果和波形可以存放在存儲器的測。他們可以立即印刷使用傳統的打印機或移動到電。浪涌測是使用最新IGBT技術。
