Looks like you are not drawing any power or the current transformer isn't attached properly. Make sure to have the current transformer attached on ONE of the TWO wires (Important to only put ONE of the power wires through the Current transformer hole. Either the Live or the Neutral but NOT BOTH). And then make sure the device is drawing some power.
