Carrying case for mass set
(oponal)
Theorecal starng value; corresponds to the pressure value generated by the piston or the piston and its make-up weights (by
their own weight). To opmise the operang characteriscs more weights should be loaded.
2) The smallest pressure change value that can be achieved based on the standard weight set. To reduce this, a set of trim
masses is also available.
3) The accuracy from 10 % of the measuring range is based on the measured value. In the lower range, a ixed error based on 10
% of the range applies.
4) Measurement uncertainty assuming reference condions (ambient temperature 20 °C, air pressure 1,013 mbar, relave humid-
ity 40 %). orrecons must be made if required.
