DUT/Reference Comparison Run Screen Fields
LABEL
DESCRIPTION
Red, Blue, or
Green Circular
Indicator
Displays to indicate the current GFS tolerance state. The indicator is always red when an
accumulation is not active. When an accumulation is active, the indicator is one of 3
colors. Each color represents a specific tolerance state for the active accumulation.
•
Red
– Not enough time and or mass has been used to reach the starting sample
tolerance.
•
Blue
– Enough mass and time have been used to start sampling.
•
Green
– The ending sample tolerance was reached. All GFS flows are in the
final averages and the accumulation will end soon.
Inst. Mass/ Mass
When not accumulating, the instantaneous uncorrected balance mass displays for the
GFS and no mass information displays for any other field.
When an accumulation is active, the column name changes to
<Mass Used>
.
The
column indicates the depleted mass according to the GFS and DUTs. The
<%Rdg Error>
row indicates the error as determined by comparing the integrated DUT mass used to the
GFS mass used.
Inst. Flow /
Average Flow
When not accumulating, the GFS has no instantaneous flow. The instantaneous value
measured by the DUTs is listed in this column. There is no error information when an
accumulation is not active.
When an accumulation is active, the column name changes to
<Average Flow>
.
The
GFS rolling average flow displays along with the average flow of each DUT. The
<%Rdg
Error>
row indicates the error as determined by comparing the DUT Average flow to the
GFS flow.
Best Fit Flow
When not accumulating, this column does not display information. There is no error or
best fit flow when an accumulation is not active.
When an accumulation is active, the GFS best fit flow displays along with the average flow
of each DUT. The
<%Rdg Error>
row indicates the error as determined by comparing
the DUT Average flow to the GFS best fit flow. This error comparison is valid when the
GFS is running at higher flows or in any situation in which AutoZero was not activated
during the test.

DEVICE OUTPUT RUN SCREEN
A Device Output Run Screen is created for each non-
DHI
device. All outputs of
a device that are in use have a final output display on one row and all
corresponding raw outputs on the next row. The label next to each output is the
specified
<Final Output Label>
and the raw output type defined in the output
specific setup of the device.
Controllers display
<Final Set>
fields with white backgrounds. Right-Click these
fields to enter a new target output value. Entering output information into these
fields automatically updates the target (setpoint) of the controller. Any associated
remote commands are automatically issued by
GFS Tools
to set the entered
target. It is assumed any output entered is in the current display unit of measure.
Outputs that require manual entry have a white background for the
<Raw
Output>
field. Entering a value in these fields automatically updates the
<Final
Output>
. It is assumed any output entered is in the current display unit of
measure.
Devices that have a remote interface also support the use of Spy Windows
(see
5.1.5.8). These display output specific commands and responses used by
GFS
Tools
to communicate with a device. Each output has it’s own Spy Window.
This makes it easy to view the commands used to generate a specific output or
response in
GFS Tools
. To view a Spy Window,
click the
<Final Output>
of any
output and select
[Spy Window]
from the popup menu.
