Functional Specifications
Accuracy specifications good for 75°F±5°F, relative humidity less
than 70%. Accuracy specified as ±% of reading ± number of
least significant digits. For example if the actual parameter is 100
and the accuracy is specified as 1%±3, the measurement could
be as high as 101.3 or as low as 98.7 on the 200 scale.
