Accuracy Specifications

Accuracy is specified for a period of one year after calibration, at 18 °C to 28 °C (64 °F
to 82 °F), with relative humidity to 80 %. Accuracy specifications are given as: ±([% of
reading] + [number of least significant digits]). Accuracy specification assumes ambient
temperature stable ±1 °C.
