4.3/ METROLOGICAL SPECIFICATIONS

The accuracies, given below, are expressed in ±(X% rdg + C), where rdg is the value read and
C a constant (expressed in physical units or in number of units of last digit). These accuracies
correspond to measurements made in the reference conditions:
- Temperature: 23°C ± 1 °C - Relative humidity: 45...75% RH
