‡ Higher resolution can be achieved via input scaling.
* After 20 min. warm-up, @ 5 samples 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 controller and probe errors. Accuracy
may be improved by field calibrating the controller readout at the
temperature of interest.
