Note: The values entered in the “Standard” column below are the Reference Thermometer readings for each
channel. Calculate your Limits of Error by: first add a factory determined offset of 0.06°C to the “Standard” value,
then add/subtract 0.11°C from the result to determine upper/lower limits. See section 4.2.1 paragraph 15 for an
example calculation.

The estimated expanded uncertainties are based on a standard uncertainty multiplied by a coverage factor K=2,
providing a level of confidence of approximately 95%
2
Published temperature uncertainty values can only be achieved if the temperature of UUT is known within 40mK.
Customers performing CJC adjustments in their facility will need to calculate their own CJC uncertainty.
