* After 20 min. warm-up, @ 5 sample per second input rate. Accuracy is
specified in two ways: Accuracy over an 18 to 28ºC and 15 to 75% RH
environment; and Accuracy over a 0 to 50ºC and 0 to 85% RH (non
condensing) environment. The specification includes the A/D conversion
errors, linearization conformity, and thermocouple ice point compensation.
Total system accuracy is the sum of unit and probe errors. Accuracy may
be improved by field calibrating the unit readout at the temperature of
interest.
** These curves have been corrected to ITS-90.
