    The easiest way is to have a low resistor value in serie with the Load and measure the voltage drop accross the resistor... and do the according math


    I = E/R


    EDIT : and if you want to read high current, you can also use current transformer and read voltage across the secondary winding.

    It's not a bug, it's a random feature.
    There's no problem, only learning opportunities.
