Hi,
I am having a similar problem with a different CT though. Are you connecting your multimeter directly on the output wires of the CT? Have you tried to connect first a small resistor (e.g., 100 Ohm) and try detect any current or voltage in parallel? And what are you trying to measure directly? AC current or AC voltage?
One idea might be that the current flowing is so small that you cannot get any value out of it. Only if you try the circuit on the diagram on this page (or of the version 3 ) then you might be able to read something in arduino.

Thanks and hope you find a solution to this.
