Heat Effects on Spirit Levels

[vtcnc]

so what it says is the spirit size is different, meaning the reading of out of level is off. But level is not affected. the change is not one side or the other, only a non level item reads off. In other words if its .0005 it might be off by .001

Right. Actual level is not affected if the reading is affected by temperature. What is affected is the action you take when a misreading occurs. So if it is off by .001 and actual is .0005, then you may shim the item out of level by .0005 if you make a misreading.
