A temperature measurement requires an uncertainty of 2C (5%) at a temperature of 200C. A standard T-type thermocouple is to be used with a readout device that provides electronic ice-point reference junction compensation, and has a stated instrument uncertainty of 0.5C (95%) with 0.1C resolution. Determine whether the uncertainty constraint is met at the design stage.
