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.
