LBQ-III leakage protection tester Introduction Wuhan Guo Ming Branch Electric Power Co., New LBQ - Ⅲ leakage protection tester is my company in type LBQ-II based on independent research and development to upgrade type tester. Tester internal isolation using the latest FireWire technology, the use of safer and more secure. The product effectively eliminate the genotype LBQ-II FireWire connection and ground fault caused by electrical breakdown endanger safety hazards testers, test time is more accurate. This product is mainly used to test residual operating current leakage protection, leakage current and the leakage action without action time, the test current is divided into ten stalls 0-500mA time test range 0-999.9ms, 16 位 ??character blue LCD The tester is a handheld, small size, light weight, easy to carry, is the site of various leakage protection or indoor testing best test instruments.
