Operation
\
Prepare to Run the Test
1. Install your specimen in the triaxial cell.
For the details on this procedure, refer to the installation section of your
triaxial cell manual.
If pore pressure becomes higher than confining pressure — even for a
second — your specimen will be damaged.
Always keep confining pressure higher than pore pressure.
2. Apply a confining pressure to the specimen.
Always keep confining pressure higher than pore pressure.
For details on this step, refer to the operation section of confining pressure
intensifier's manual.
3. If your triaxial cell has pore pressure valves, make sure they are open.
