Accuracy
Refer to the “Specifications” section for operating conditions and temperature coefficient.
Accuracy is specified as follows: ± (a percentage of the r a fixed amount) at 23 °C ± 5 °C
(73.4 °F ± 9 °F), 0% to 75% relative humidity.
Accuracy is specified from 5% to 100% of the range unless noted otherwise.
