Operation

Control Panel

The following figure shows the operational controls, superimposed on the front
panel hydraulic schematic. The following table describes items 1 through 8,
shown in the figure.

The table lists the operational effects of each individual control. However, note
that performing the various operations listed in the table usually involves the
manipulation of two or more of the controls.

Confining Fluid
Output

Adjustable hand-valve. Turning the valve counterclockwise toward Open

allows air to be vented from the triaxial cell to the reservoir when filling the
cell with fluid. The valve must be closed before pressurizing the triaxial cell.

Confining Pressure
gage

Analog gage. Indicates pressure inside the Triaxial Cell, scaled in pounds

per square inch (psi).
