Uncertainties in the table are maximal uncertainties of RTD sensor simulation. Actual uncertainty for each set value of
simulated temperature is determined by uncertainty of relevant resistance. Actual temperature uncertainty is displayed on
the calibrator display. Actual uncertainties are always lower than those in above table.
