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
4.3.1 Receive mode
Measurement rate of each instrument 2 measurements per second
