4.7.3.3
Test Reference
A test reference can be entered into the 'Test Reference' text box. This may be a
specific sample number, batch number or a LIMS related reference if required.
4.7.3.4
Auto Analysis Selection
When this is selected the auto analysis will be carried out straight after the heat up cycle
is completed and all the deformation images have been captured, hence the whole test
from heat up through to analysis is one continuous process.
4.7.3.5
Start Test
When you are satisfied that the information you have entered is correct, select 'Start' to
run a CAF test.
Selecting 'Start' will automatically set the furnace controller to 'Run' and start the
furnace program. The yellow 'test in progress' light will illuminate on the control panel.
The green Standby Mode indicator will go out.
Note
: Do not open the furnace door when the 'test in progress' light is illuminated. See
The furnace will dwell at its current setpoint (start temperature) for 5 minutes then
ramp to the selected target temperature at the pre-selected ramp rate.
Note
: Avoid operating the furnace at unnecessarily high temperatures and ramp rates.
See section 4.7.2.2.
When the furnace reaches the preselected 'Start Image Capture Temperature' images
will be saved at the pre-selected 'Image Capture Interval' up to the ramp target
temperature. As the images are stored the black text box will flash across the top of the
image window.
Both the 'Configure' and 'Analysis' tabs are disabled once recording has started.
4.7.3.6
Start/ Stop the Program
The furnace controller program can also be started and stopped independently of the
CAF test software:
To start the program: press the Run/ Hold button (•) on the front of the controller, the
word RUN will illuminate at the side of the button to signify that the program is running.
To stop the program: hold the Run/ Hold button (•) on the front of the controller until
both the words RUN and HOLD at the side of the button are no longer illuminated.
4.7.4
Analysis: Automatic and Manual
The analysis tab is used to open previous test images, carry out automatic or manual
analysis of the test pieces and record the characteristic deformation temperatures.
During the CAF test, images are stored in the form of 'Date-Time-Temperature-
Sequence.tif' files in the folder headed with the 'Test Name'. These images can be
viewed and analysed either automatically or manually by opening the folder with your
test name (see section 4.7.3.2). The file folder is constructed as shown in fig 16.
The stored images can also be replayed immediately after a heat up cycle is complete.
The images can then be analysed automatically or manually if required.
