    I have the 50amp version of your 20amp DC volt/amp meter panel, the YB4835VA, which comes with a 50A shunt.

    Q: For checking current that is less than 20 amps is the shunt STILL required?

    It does not seem to work on low amperage unless the shunt is connected (even when tested with 1.0 amps).

    Thanks in advance

    Hello Kris,
    We wonder if you mistake the item. YB4835VA is AC meter. It has a current transformer instead of shunt.
    Would you please send a product link for confirmation?
    Best regards.

    The link is: https://www.amazon.com/DROK-Multimeter-Three-Digit-Voltmeter-Three-wire/dp/B01M9CJYQJ/

    But the wiring diagram on the backside definitely states it as YB4835VA. And it works as a DC meter. Maybe the wrong label was used by mistake?

    Dear Kris,
    Thanks for your reply.
    Actually YB4835VA is not a reference part number，so we can’t confirm item with it.
    About the meter you bought, no matter how large the current is, it must be connected with shunt.
    Best regards.

    The product’s weblink states: “IF THE CURRENT IS HIGHER THAN 20A, A SHUNT IS REQUIRED TO USE”. So doesn’t this mean I do NOT need the shunt if the current is LESS than 20A?

    Hello Kris,
    Please kindly notice this item has 20A specification. https://www.amazon.com/DROK-Multimeter-Three-Digit-Voltmeter-Three-wire/dp/B01M7R7JPJ/?th=1
    So if you buy one with over 20A range,shunt is necessary.
    Best regards.
