3.2 Operation .
3.2.1 Weight Pieces .
Stack the weight pieces onto the bell depending on the pressure value that is required.
It is usually best to start with the heaviest weight so that the centre of gravity is as low as possible.
Each component is identified by a consecutive number. In the calibration certificate to each number
the resultant pressure assuming reference conditions is listed.

Example: weight piece no. 5 generates a pressure value of 200.6150 bar
with its weight value of 4.09305 kg assuming reference
conditions (room temperature 20°C, air pressure1013 mbar,
relative humidity 40 %)
The pressure that will be achieved thus corresponds to the sum of the basic weight (piston), the
bell and the weight rings.
