    Normally I'd say, "Buy it and read the instructions". This one says, "English Manual/Spec: No"

    That changes my opinion to, "Don't buy it".

    The power inputs are marked so the other 2 wires must be to measure the current.

    If it says negative current just swap the current leads with each other.

    What do you want to do?
    Use it to be a 0~5A Ampere Meter.

    Power +Vcc → Ampere Meter → +Vcc (BreadBoard).
    Power Gnd ← Gnd (BreadBoard)
    The resolution will be 10mA, from 0.01A ~ 5.00A or 0.01A ~ 4.99A.

    Use it to be a 0~5V Voltage Meter.
    Ignore the internal impedence of Ampere Meter.

    Power +Vcc → 1Ω → (+) Ampere Meter
    Power Gnd ← (-) Ampere Meter
    The resolution will be 10mV, from 0.01V ~ 5.00V or 0.01V ~ 4.99V.
    If you adding the internal impedence of Ampere Meter, then should be reduce the value of 1Ω.
