Yeah, if you've ever heard jokes about "the first pancake"[0] or burnt your pancakes when you get distracted by the rest of breakfast, do yourself a favor and set your griddle to 325F/160C.
Your pancakes can sit at 325F for a long time before they burn, and that alleviates the fear of burning that leads you to flip that first pancake too fast.
I always make "test pancakes" until my griddle is just right, as I don't have a fancy temperature control. A drop of batter will behave just like a full-size pancake if you know what to watch for, a teaspoon if you don't.
I don't have a fancy temperature control, but I had just moved from gas stove to glass top electric* and and I got tired of waiting sooo long to hopefully get to a good cooking temp, only to ruin things by finding out the answer was no.
So a bought a hand-held laser-pointer-temperature gun at the hardware, wow, it's fantastic. Now I know what temps are for what (it's remarkably similar to the oven, 325 to 450) and I know how to find them and how quickly on my stove.
*what is with Miele appliances, they all suck, range, convection oven, microwave. the UIs are impossible.
there is no first pancake problem if you only use your griddle for pancakes, that comes from having to use a pancake to get off whatever horrible things you've put on there in between uses. (and btw, your eggs will cook much easier if you dedicate an egg pan)
325's a good number but I prefer a 350 to 375 with a little urgency, it better gets that "deep fried crispy" around the outside, and stops the already flipped side from just getting steamed to death.
