    Nron,

    If you go to the page below and scroll down I think you'll find what you're looking for only it's in pdf files not drop down charts. lots of other info on that page also.

    I hope the site I offered still proves to be helpful though :)

    thermocouple dropout

    I think you will find a normal t'couple read under load around 14/15 and a dropout of 2-4..I believe any dropout exceeding 4mv will indicate power unit has resistance
