Table 16. DUT Definition Editor, [Header] Tab Fields
FEATURE DESCRIPTION
Record Type
(required drop
down list
selection)
There are two types of DUT Definitions:
•
Individual DUT Definitions are intended to define a specific, individual DUT. They
include a unique DUT serial number and identification value. This type of DUT Definition
does not require new entries during test initialization (see Section 7.2.1.5).
•
DUT Profile Definitions are intended to define a general DUT type. They do not
include serial number and identification values. DUT profiles are useful when several
DUTs of a specific type will be tested. Instead of creating multiple DUTs all
differing by serial number and/or identification only, use a DUT profile. This type of
DUT Definition requires that the DUT be identified during test initialization (see Section 7.2.1.5).
One definition type must be selected. Default is Individual DUT.
Manufacturer
(required drop
down list
selection)
The DUT manufacturer is selected from the drop down list box. The manufacturer selected
along with the
<Process Gas> and <Calibration Gas > determine the default DUT gas
conversion <K Factor> . Therefore, the manufacturer is a required field.
Gas conversion factors, often called K factors, are used when a DUT cannot be tested
with the gas with which it is normally operated. K factor definition and uncertainty are
the responsibility of the DUT manufacturer (see Section 15.1 and the molbox Operation
and Maintenance Manual,
[K] Section).
If the desired manufacturer is NOT in the list of manufacturers, then the <Process Gas Editor>
can be used to add this manufacturer and the allowable process gases and associated
K factors (see Section 15). The
[Tools] menu contains a link to the <Process Gas Editor> .
Alternatively, a new manufacturer can be entered manually by choosing the <Add
Manufacturer> option at the beginning of the list. Manually entered manufacturers are
automatically added to the drop down list (alphabetically). Use the [Tools] , [Options] ,
[Maintain Lists] tab to delete unwanted manufacturers added in this fashion (see
Section 11.4). NOTE: Manually added manufacturers do not contain K factor
information as do manufacturers added with the <Process Gas Editor> . As a result,
the <K Factor> field does not automatically refresh with each new <Process Gas> and
<Calibration Gas > selection. Manually added manufacturers are typically used with
DUTs that do not use K factors.
The default Data File directory naming preference can use this entry to create the
directory for Data Files created when this DUT is run (see Section 11.8).
Model
(required drop
down list
selection)
The model number or name for the DUT can be selected from the drop down list or a new
model can be entered manually. Manually entered models are automatically added to the
drop down list (alphabetically). Use the
[Tools] , [Options] , [Maintain Lists] tab to delete
unwanted models from the list (see Section 11.4). DUT Definitions that contain a deleted
model are still valid. The default Data File directory naming preference can use this entry to
create the data directory for Date Files created when this DUT is run (see Section 11.8).
Serial Number
(optional text entry
field, Individual DUT
Definitions only)
Write in the DUT serial number. DUT Profiles do not include a serial number during the creation
of the DUT. The default Data File directory naming preference can use this entry to
create the data directory for Date Files created when this DUT is run (see Section 11.8).
Identification
(optional text entry
field, Individual
DUT Definitions
only)
Write a DUT identification, if desired. This field can be used for internal tracking of
DUTs or to record other information. Any combination of information can be entered
into the ID field. The value entered will be included in the test Data Files and can be
included in reports. The default Data File directory naming preference can use this entry
to create the data directory for date files created when this DUT is run (see Section 11.8).
Profile Type DUT Definitions do not include a device ID.
Process Gas
(required drop
down list
selection)
The process gas is the gas with which the DUT is intended to operate in its actual application.
This is a required field since it is used to determine the default gas conversion “K” factor for the
DUT (see Section 15.1). If a gas is not included in the drop down list, the gas can be added in two ways:
1. If the selected <Manufacturer> was created with the <Process Gas Editor> , the
<Process Gas Editor> must be used to add the gas (see Section 15). Use the
link to the Editor found in the [Tools] menu.
2. If the selected <Manufacturer> was manually entered, use the <Add Gas> option at the
top of the list to add the gas. Realize that no K factor information will be provided by
COMPASS for this gas. The K factor must be manually entered in the [Test] tab
(see Section 8.5.6).
