Yeah, no adjustments on that model. It is fixed to an E value of .95
I believe if you wanted to test it, you could put a couple pieces of printer paper (maybe 3-5 thick) over your granite, let that sit for a bit, then measure again with your gun, aiming at the paper. The paper has a much closer E value to your gun. I don't believe there would be any issues with the granite underneath throwing off the gun.
That would be just to get the temperature of your basking surface with your gun if you were curious. But of course, you could keep the granite and just use the temp probe instead to confirm your basking surface.
