6.3.8 DUT MANIFOLD
When the optional DUT manifold is active in the system setup, the
<DUT Manifold>
display
is available to monitor and control the devices connected to the manifold. When the vacuum
pump and ion gauge are active, their outputs display at the top and bottom of the form.
Activate the manifold and associated devices by using the
[Config], [System Setup],
[Options]
see Section 6.6.2.2. When a device is activated, it is available for use by FPG
Tools. It does not mean that the device is automatically turned on. Use the manifold toolbar
to control the vacuum pump and ion gauge as need.
The manifold display also acts as a pressure schematic. Based on the state of the valves on
the manifold display, the colors of the connecting tubes will change to reflect the
current pressure. Table 11 lists the colors and their correspondence to pressure.
Double-click any valve to toggle the current activation state.
Do not toggle valves on the DUT manifold without considering the impact the changed
state may have. In some cases, a large pressure differential may exist. This can damage
any device pneumatically connected to the manifold, including the FPG.

Color Scheme
COLOR DESCRIPTION
Red
Pressure from the upper chamber of the FPG.
Blue
Pressure from the lower chamber of the FPG.
Black
Vacuum pressure generated by the manifold
vacuum pump.
Gray
The current pressure state is undefined. This
typically occurs when valves are adjusted to
completely isolate the gas.
