‡ Higher resolution can be achieved via input scaling.

* 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 meter and probe errors. Accuracy may

be improved by field calibrating the meter readout at the temperature of

interest.
