Since I just recently bought a press (used, from here), the first thing I did ewwas measure it's temperature.

I used a candy thermometer (dare I say, a digital one from the supermarket), placed on the pad all the way in (left about an inch sticking out), closed it down and turned up the thermostat. Step by step, measured the difference.

And yes, mine is way off... Something to check into later. It reaches mounting temp and that's all that counts at the moment...
