1) For ranges < 100 mbar there is an accuracy of 0.2 % FS.
2) It is defined by the total measurement uncertainty, which is expressed with the coverage factor (k = 2) and includes the
following factors: the intrinsic performance of the instrument, the measurement uncertainty of the reference instrument, long-
term stability, influence of ambient conditions, drift and temperature effects over the compensated range during a periodic zero
point adjustment.
3) Reference conditions: 15 ... 25 °C [59 ... 77 °F]
