For example, the standard tolerance of Type J is ± 0.75 percent. If the temperature being measured is 538°C, the tolerance is ± 0.75 percent of 538°C, or ± 4.0°C. To determine the tolerance in degrees Fahrenheit, multiply the tolerance in degrees Celsius times 1.8. 2 Thermocouples and thermocouple material are normally supplied to meet the tolerances specified in the table for the normal specified range. The same materials, however, may not fall within the cryogenic tolerances in the second section of the table.
