Warranty co. says, "Inspector's 1 minute test along with a light tester is inferior and should be tested on high for 2 1/2 minutes this should boil water 212°F in most units."
Unit in question will only get to 200°F by their own time and test,
"but that is close enough" they say.
Notice there is no reference to the starting temperature?
That would also be something to consider when testing to a specific temperature over a certain time; 40 degree water takes longer to reach boiling than 80 degree water.
