2. Test Type Screen: This screen has the possibility
of seven different test types to choose from
. The D3241 ASTM test is always active
[Figure 33]
and the button cannot be deactivated. Single,
Breakpoint 1 and the 4 Custom tests are activated
from the 'Preference' screen.
Figure 33
A. ASTM: A D3241 test commences following
the mandatory test information entry. This test
is 150 minutes with a flow rate of 3ml/minute.
These values cannot be altered. The tempera-
ture defaults to the value set under 'Prefer-
ences' and can only be altered through the
'Preferences' screen.
B. Single tests: This selection allows the opera-
tor to set parameters for test duration, flow rate
and test temperature for one run. The param-
eters entered are not stored.
C. BreakPoint 1: Breakpoint 1 runs a series of
automated tests, sequencing from the visual
tube reading numeric value only. All tests
run 150 minutes. Configuration allows for the
operator to choose the initial control tempera-
ture (between 180–380ºC) for the series of
tests. The operator enters a tube rating value
for each test in the series and the program au-
tomatically sets up the parameters for the next
test. Each subsequent test will automatically
increment 10ºC if the entered tube reading is
<3 (0-2). There is one exception to the auto-
mated temperature increase and that is on the
second run. The operator is given the chance
to reenter his starting temperature to a higher
value if he feels the initial temperature setting
was too low. Once a reading of 3 or greater, a
peacock [P], or abnormal [A] rating is en-
tered, the final test in the series is initiated at a
temperature of 5ºC below the previous run. All
results are compiled into a single data file.
NoTe: Only tube rating entries of <1, 1, <2, 2,
Test Selections
Section 3: Software Operation
<3, 3, <4, 4, and [A] abnormal or [P] peacock
are accepted for the breakpoint tube reading.
D. Custom buttons 1-4: Custom 1-4 buttons
allow the user to store both the test header in-
formation and the test parameters as a unique
test name. This information is retained with the
button selection until it is overwritten. Select-
ing a test type will advance to the respective
configuration screen
3. Configuration Screens: All test types require
configuration prior to starting. Data File Root
Name, Lab, Operator, Tube ID Fuel Type and
Fuel ID fields can be entered by the operator,
however tube ID and the Fuel ID must be entered
before the configuration screen will display a
forward arrow allowing program advancement
. Some test configurations allow for entry
[Figure 34]
of test duration, flow rate and test temperature.
All four custom configuration screens have
one additional entry field for the button name.
Information entered in the Configuration screens
is considered the header for the generated data
files and will appear on both the printed report
and the electronic file. The back arrow at the
bottom right returns to the 'Test Type' screen. The
forward arrow on the bottom right will only appear
once the mandatory configuration information has
been entered. The Instructions button on the lower
left opens a window with generic instructions for
setting up and running a test. Please refer to the
method for specific instructions.
