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 table from a calibration certificate page 2:

Example: weight piece no. 5 generates a pressure value of 200.6150 bar
 The pressure that will be achieved thus corresponds to the sum of the basic weight (piston), the
bell and the weight rings.
