But doesn't your PID give you this light? Mine does, aren't they all pretty much the same? The duty light or whatever, bottom left. Lights whenever it sends voltage to the SSR.

Just saying.
To back up P-J, SSRs switch current, not voltage.

Your light switch turns voltage on & off.

But SSRs are more like a stove top eye control with two settings - full on & very, very low. So low that when your element is connected and the SSR is turned "off" you will measure little or no voltage across the element.

But disconnect the element and you will read a voltage - how much depends in how "off" the SSR really is and your meter's input resistance. Also, there is definitely enough voltage past a "off" SSR to shock you!

I can back up everyone here. I had similar issues when I wired mine and was doing a final wire check. Crazy voltages across my SSR. Couldn't figure it out for the life of me. Upon the sage advice of my eBrew brethren, I connected the element and everything worked as it should. Measure across the SSR terminals when the element is wired in and you should be golden.
