Hydraulic Pressure Target Window
The picture below illustrates how the system keeps the pressure inside the pressure target window while holding the pressurize button pressed.

1 | Min bolt tensioning pressure (y) |
2 | Hydraulic pressure target (x) |
3 | Hydraulic pressure hysteresis level (x-y)/3 |
Calculation
Hydraulic pressure target (x) = Min bolt tensioning pressure (y) × Hydraulic pressure target factor (k)
Hydraulic pressure hysteresis level = 1/3 of the distance between Hydraulic pressure target (x) and Min bolt tensioning pressure (y).
The pressurization starts at this level to keep it above the minimum level.
