Nominal is 35 ohms should blink the light and bring the needle to the
extreme left of the overheat zone, +/- one needle width.

265 ohms should (eventually, maybe with a tap or two) bring the
needle to the bottom of the "transition zone" again +/- one needle width.

If you have the gauge out you'll see three little lines that you can
sight along the needle to; nominal, +limit, -limit for each of the
two calibration points.
