I am taking measurements with REW but have a small problem.

As soon as I plug in an RCA to 3.5mm jack cable into the output connecter the guage reads maximum. My PC still manages to get proper readings so I am curious as to why this is happening.

Thanks in advance.

The PC input is carrying supply for a condenser mic. Try the other channel, sometimes the supply is only on one channel.

Same thing happens to my radioshack SPL meter, tried both left and right but still reads max..

I'm planning on calibrating for the first time today. So I'm still reading up on everything but my RS SPL has a switch for SPL range... 80-70, 70-60, 60-50. I've noticed it the switch is set lower then the output volume the signal meter reads MAX. Could this be the issue?
