1) Refer to the working range of the humidity sensor. 2) Can be easily changed by software. 3) Refer to accuracies of calculated values (page 152)*) The accuracy statement includes the uncertainty of the factory calibration with an enhancement factor k=2 (2-times standard deviation). The accuracy was calculated in accordance with EA-4/02 and with regard to GUM (Guide to the Expression of Uncertainty in Measurement).
