Note : The percentage apply to the temperature being measured. Little Information is available to justify establishing special tolerance below 0 celsius.
Values for Type E and T are suggested as a guide. The fahrenheit tolerance is 1.8 times larger than tolerance at the equivalent celsius temperature. The
percentage tolerance apply only to temperature that are expressed in celsius. Tolerances are always whichever is greater. Data are based upon the
