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.

Uncertainties in the table show range of the uncertainties of TC sensor simulation in specified range. Actual uncertainty for
each set value of simulated temperature is determined by uncertainty of relevant DC voltage. Actual temperature uncertainty
is displayed on the calibrator display.
