    Hello William T. Ward,
    Thank you for your reply.
    So long as the input voltage for the meter is the power frequency voltage (city power).
    Your plan will be Ok.

    in reply to: Parallel circuit of energy meter #6594

    Hello Félix,
    If the measuring current is over 20A, you should use the 50A module with external shunt.
    The shunt should be connected series to the negative of the load.
    The value of the shunt is 50A/75mV.
    Here is the wiring diagram of the 50A module:
    Wiring diagram_200140
    Hope this can help you.
    Best regards

    in reply to: 8-22V to 1-15V Buck Convertor Info/Datasheet #6588

    Hello Matthew,
    Thank you for writing in.
    There is no fuse or capacitor inside the product.
    But if the converter is broken, there will be no output from the converter.
    The possibility of high voltage output is very little.
    And here the PDF file is the datasheet of the product:
    DATASHEET_090010
    Hope this can help you.
    Best regards

    in reply to: calibration of AC 100-300V 100A Digital Voltage Current Multimeter #6570

    Hello amartin,
    Thank you for writing in.
    There are two calibrating potentiomentes inside one for ampere calibration and the other for voltage calibration, please check the following image:
    Calibration_100105
    If you extend the cable, it will affect the accuracy of the current reading.
    So sorry that we do not have a AC meter for AC100-300V-10A.
    Beg your understanding and hope this can help you.
    Best regards
