[SUPPORT HARDWARE]
The
[Support Hardware]
menu choice accesses the
Support Device Editor
. All devices
that are not specifically DUTs are considered support devices. Support devices are typically
flow controllers and analog power/control instruments. These instruments are the
Output
Source
of DUTs that have a voltage output or MFCs that require an analog set point.
The
Support Device Editor
provides features to create, edit, view and remove
Support
Device Definitions
. When selected, the last accessed Support Device Definition displays.
To edit an existing Support Device Definition, use the Editor Toolbar icons to select the
desired definition. Then simply edit the desired fields. Press the Editor Toolbar,
[Save]
icon
to save the changes.
Support Device Definitions are defined and maintained in the same manner as DUT
Definitions (see 5.5.3).
This editor is functionally identical to the DUT Definition Editor accessed using the
[Setup][DUT]
menu choice. The only difference is that the list of
<Device Type>
options is different.

[REFERENCE GAS CYLINDER]
Reference gas cylinders are added and removed by using the
[Setup][Reference Gas
Cylinder]
menu choice. This menu evokes the
Reference Cylinder Editor
. The basic
editing process is similar to other editors in
GFS Tools
. The actual cylinder to use during a
test is selected during Test Initialization. Refer to section 5.7.5 for details on the math
associate with buoyancy corrections applied to the reference gas cylinder.
