Features: ETCR9200 H/L Voltage Clamp Current Meter has broken through the traditional structure, which is specially well-designed for measuring high voltage current, adopt latest CT technology and integrated mask digital technology, composed of special clamp current meter and high voltage insulation rods. Without insulation rods, it can used as high-precision low-voltage clamp meter and leakage current meter, can accurately measure the current or leakage current of 0.01mA. Specifications:       Function             H-voltage AC current measure, L-voltage AC / leakage current measure              AC current monitor online            Power Supply    DC6V Alkaline Dry Battery ( 1.5V AAA X 4 ) ( Not included package )        Test Method    Clamp CT, Integral Method; hook the meter on the line to test, save the physical power of user        Clamp Diameter    Φ68mm        Range of measurement    0.00mA~1000A(50Hz/60Hz Automatic)        Resolution    0.01mA        Shift    0.00mA~1000A Automatic Shift        Test Accuracy (23& 8451;±5& 8451;,≤80% RH)    0.00mA~299mA: ±1%±3dgt        0.30A~49.9A: ±1.5%±5dgt        50.0A~199.9A: ±2%±5dgt        200A~600A: ±3%±5dgt        601A~1000A: ±4%±5dgt        Display Mode    4 digital LCD display        LCD Dimension    Tester: LCD: 35mm×21.5mm        Meter Dimension    Tester: 218mm×135mm×60mm        Sampling Speed    About 2 times/second        Data Storage    99 Groups, during storage, the symbol “MEM” gives indication, “ FULL” mark will flash to indicate the memory has been full        PEAk Maintenance    Automatically maintain the height of the test value, usually in the test mode pressPEAK, LCD top right corner will display “ PE ” , that is, to keep open the PEAK function, then press PEAK key to cancel this function key        Circuit Voltage             Test insulating sheath wires ( ≤60kV ) and bare wire t ( ≤35kV )               ( operated with insulation rod )            Data Preservation    Under general test mode, press HOLD button to preserve data, “ DH ” symbol display.
