Buyers must see:

     Split: Green terminal is connected to the AC transformer CT, red, black wire is connected to the AC voltage measurement, do not pick the wrong, wrong will cause permanent damage to the instrument
     Note: This table uses capacitor step-down design principles, because the higher the frequency the smaller the impedance of the capacitor, it is not suitable for use in high-frequency electronic speed control, non-mains frequency sine wave, or other high-frequency components of the occasion, or else easy to burn !!!
     When are unsure, please communicate with the frequency of the output waveform of the test equipment and customer service
     In the selection of the range, the range is not the bigger the better, the greater the error, the greater measuring range is recommended for the 1.5 or 2 times the actual value of the test can be

product manual:

    Split: easy installation, transformers and instrument separation, transformers can be installed in accordance with the actual position measurement (can be lengthened transformer secondary side of the lead, to achieve the desired mounting position)
    Fixed: fix the current transformer meter above
    AC voltage, current meter with screen, color, dual display, highlight large font;
    Instrument wiring is simple:
        Two-wire: No need for additional power supply connected, red and black to simultaneously measure voltage power to the header (without sub-polar)
        Current test no additional purchase of transformers, instrument transformers comes with high precision
    L set in the header trimming potentiometer can be self-calibration voltage, current error
    Split Transformer meter with a cover, use safer, more convenient, more at ease! ! !
    Note: instrumentation wiring sequence is: First, connect the current loop line, and finally connect voltage 220V, 220V power supply after turning on, you can not touch any part of the circuit and the back of the instrument to prevent electric shock hazard.
