Introduction
This chapter contains theory of operation principles and information for the Controller
and the Intensifier.
Controller
The main function of the Controller is to have a user set a target pressure then accurately
control and measure applied pressure to a unit under test (UUT). When a user sets a
target pressure, the Controller uses the user supply selection to determine whether to use
the internal pump, an external source, or both as follows:
•
When the target pressure is <4 psig, the Controller must use the internal pump. See
“Internal Pressure Source (Internal Pump)” on page 2-7.
•
For target pressures between 4 psig and 305 psig, the user can choose whether to use
the internal pump or external supply. This is set on the Main menu as shown below.
See “External Pressure Source (Intensifier or Nitrogen Cylinder)” on page 2-4.
Note
If the source is shut off or runs out and the External supply is
selected, the Controller will not automatically switch to the internal
pump.
