1) Theoretical starting value; corresponds to the pressure value generated by the piston or the piston and its make-up weights (by
their own weight). To optimise the operating characteristics more masses should be loaded.
2) The smallest pressure change value that can be achieved based on the standard mass set. To reduce this, a set of fine
increment masses is also available.
3) The accuracy from 10 % of the measuring range is based on the measured value. In the lower range, a fixed error based on
10 % of the range applies.
4) Measurement uncertainty assuming reference conditions (ambient temperature 20 °C, atmospheric pressure 1,013 mbar,
relative humidity 40 %). For operation without a CalibratorUnit, corrections must be made if required.
