Purging and Filling the Fluid Lines
Operation
4. Refill the Pressure Intensifier with fluid.
On the RSC, slowly turn the Manual Control to retract the Intensifier’s
piston.
Stop when the displacement signal shows a fully retracted piston.
5. Make sure the Pressure Transducer line is fully purged so air bubbles will
not be forced into the pore lines.
On the RSC, slowly turn the Manual Control to extend the Intensifier’s
piston.
Stop when bubble-free fluid begins flowing back into the Reservoir.
Now turn the Manual Control to fully retract the Intensifier’s piston.
6. On the test controller, monitor the pressure sensor output.
