Product Functions& 65306;  In the case of the tested circuit is not open-loop, measure two AC voltages, current, phase between voltages, phase between currents, phase, frequency, phase sequence, active power, reactive power, apparent power, and power factor between voltage and current. Discriminate the transformer wiring group, inductive and capacitive circuits, test the secondary circuit and the busbar protection system, read the phase relationship between the CTs of the differential protection groups, check the wiring of the meter for correctness, and repair the line equipment, etc.          Product Features& 65306;   1.Intelligent design, re3duce the complexity of operation, reduce the possibility of misoperation, with high precision, high stability, low power consumption, easy to use and other advantages.  2.Adopt voltage transformer and current clamp to input, no high voltage inside the meter, complete isolation between 2 input channels, safe and reliable.  3.Small sharp clamp is suitable for flat cable dense site  4.The test wire adopts special electric power cable, all the plug of spring rod and crocodile clip have insulated protection. The instrument is insulated with non slip sheath.  5.With USB interface, Data storage: 1200 groups. Through the system software to upload the storage data to computer, convenient to read, save, report, print historical data, etc.            Product Specifications& 65306;                                             Power Supply                                 DDC9V Alkaline battery LR61.5V AAX6PCS                                             Detection Rate                                 About 2 second/times                                             Meter Dimension                                 196mmx92mmx54mm                                             Display Mode                                 2.
