Default Engine temp measurement - EXACTLY where?

Just curious, using an infra red temp gun (laser sighted or not) - where should the gun be pointed at?

1. At the glow plug
2. Next to the glow plug
3. Anywhere in the glow plug area

Obviously from logic reasoning, the plug would be the hottest - and it will get colder as measurement is taken away from the glow plug.

So when someone has an engine running at 250F - where did they take the measurement?

Comments?

A normal Way to Check Temp , Is to Sweep from one end of the Glow Plug hole to the other in a slow motion. Most of the time the center will be your hottest point. Which is your temp.

I dont know weather its rigt or wrong, but I take my temp readings around the glow plug. I find that if I take the readings on the plug it gives a much cooler reading. Also I move my pointer in a plus+ sign patern, this usually gives a higher reading in a certains spot.

Thanks,
