Table 17: Position Interpolation Table Parameters
9.1.3 Stroke Position Parameters
For XVG/eXVG low measurement and flow control accuracy improvement, the CdA
values are calculated based not only stroke position (using stroke- CdA interpolation
table) but also on pressure ratio condition.
The following Stroke Position Table lists default values of fifteen stroke positions that
will be used in CdA values calculation. Table values are (stroke value*2
