pressures, and the values of areas obtained are plotted against the nominal pressure for

each point. A least-squares line is fitted to the plots as the best estimate value of the area

at any pressure.
There are two accepted methods for determining the balance of the two pressures. First,

the sink rates can be observed and graphed using high sensitivity sensors. Second, a

sensitive null-pressure transducer can be interposed which will display small pressure

differences directly.
When using a suitable amplifying device, the scatter in the plotted areas from a good

quality piston gauge should not exceed a few parts per million.
