    KE7308
    Portable Three Phase Standard Meter
    Accuracy : 0.05 / 0.1, Test method : terminal input or clamp CT , Protection degree : IP67, test the error of three phase energy meters and field electrical parameters of power grid

    Highlight:

    ·        Wide current range (direct connection): 0.2A to 20A, the highest accuracy of each test point is 0.05%

    ·        Calibrate the error of all electricity energy meters, checking the constant of the energy meter

    ·        Simultaneous checking of the primary meter and the secondary meter in the same loop, or simultaneously checking of the active power meter and reactive power meter in the same loop

    ·        7” color LCD display, All the parameters of each operation function can be displayed within one page

    ·        Two operation modes: touch screen and keyboard. Easy and reliable operation..

    ·        Measure voltage, current,frequency, power, power factor and phase angle

    ·        Simultaneous measure and display waveforms of three phase voltage and current

    ·        Measure ratio of CT.

    ·        Allocate clamp of 20A, 100A, 200A, 500A,1000A to directly measure the comprehensive error

    ·        Measure the 2nd - 51st harmonics of current and voltage

    ·        Display vector diagram, judge the wiring right or wrong automatically

    ·        Industrial grade engineering plastic suit case, which has a safety protection level of up to IP67.

    ·        Read the information of energy meter with barcode scanner (optional)

    ·        Battery, test lead power or external power for choices

    ·        Communicate with PC, download calibration data through USB flash disk, RS-232 port

    ·        Firmware can be upgraded through removed disk by users themselves

    ·        Save and browse the testing data
