1.Features: ETCR6000B AC/DC Clamp Leaker is specially designed for measurement of AC/DC current; by adopting up-to-date CT technology and digital integration technology. The small clamp is suitable for line densely places (electric power measurement system, the high speed rail system, car circuit overhaul, and so on), non-contact measurement, to ensure safe operation. It is a product with relatively small size, high accuracy and perfect function compared with similar leakers in the world. The leaker could be widely applied in those fields as electricity, communications, meteorology, railroad, oilfield, construction, measurement, scientific & research teaching institutes, industrial and mining establishments. it is an essential tool for electrician safety testing.  ETCR6000B AC/DC Clamp Leaker also named: DC Leakage Current Clamp Meter, Car DC Leakage Current Clamp Meter, AC/DC Clamp Leakage Current Tester. It has those functions as data holding and data storage. It obtains one RS232 interface, communication cable and software, through which historical data inquiry is available, for reading, saving and printing.    2.Product specifications:            Function     Measurement of AC/DC current, leakage current           Power Supply     Zn-Mn dry battery,6F22,9V(not included package)           Test Mode     Clip-on CT, integral mode           Clamp Size     16*18mm           Measurement Range     0mA-60.0A AC/DC           Resolution     1mA AC/DC           Accuracy     ±2%rdg±5dgt (23C±5C, below 75%rh)           Display Mode     Four digits LCD display           Dimension     LWH: 168mm×65mm×34mm           LCD Dimension     35mm×21.
