2. Click in the Thermometer Temperature field and type the current
temperature (as indicated by your calibrated thermometer) to the
nearest 0.1°C in the Thermometer Temperature field. Make
certain to use the minus (-) sign for subzero temperatures.
3. Click the Temperature Correction button to enter the temperature
reading.
NOTE If you input a temperature but do not click the Correction button, the input
temperature value will be stored in the database as the actual tempera-
ture for the test.
4. Wait for the instrument to stabilize at the new temperature for the
desired time period.
5. Continue with the Yield Stress and Viscosity test procedures.
NOTES The Temperature Correction button option is only active at the conclusion
of the temperature profile and prior to yield Stress or Viscosity testing.
If the amount of the Final Temperature adjustment is greater than the
tolerances specified in the profile, the temperature probe and CMRV cells
should be recalibrated per the manual procedure.
If you do not enter a Thermometer Temperature, the final profile tempera-
ture will be recorded as the actual temperature for the test(s).
Displaying a profile graph
Graphing the current profile To view a graph displaying time/temperature data from the current
profile during CMRV testing, click the View Running Profile button
from the Instrument View window to view updated data from the current
test in graph format (X axis = time; Y axis = CMRV sample tempera-
ture). The graph information is updated approximately every 10 minutes.
Graphing earlier profile data
To view a graph of time/temperature data from a previous test (viscosity
or yield stress), just configure an analysis for the data (see chapters on
Analyses) and right-click anywhere inside the data window for the
analysis. Then click the Display Temperature Graph popup menu
option.
Mouse-over display features After you have displayed the profile graph, you can move the mouse
cursor over any portion of the graph and the status bar at the bottom of
the Profile Graph window will dispay the Time, Actual Temperature
and Target Temperature values for that point in the profile.
Zooming in To view a section of the profile graph in greater detail, click and drag
(press and hold down the left mouse button) the cursor to "draw" a box
around the desired graph area. Then release the mouse button. The graph
will be redrawn to include only the selected area.
