Starting a profile
1. If the View Instrument window is not open, click Main/View
Instrument and select the desired instrument type (MRV) and
configuration from the View Instrument window. Then click OK.
Polling instruments If you are unable to select your CMRV from the list of available instru-
ments in the View Instrument window, make sure the instrument is turned
on and warmed up (see Chapter 6); then select Poll for Instruments from
the Main menu.
2. From the MRV Instrument View window, click the Upload Profile
button to open the Upload Profile window.
3. Select a Standard or User-Defined profile from the available
profiles in the drop-down box, then click OK.
NOTES To run samples using -20°C or -25°C calibration data per ASTM specifica-
tions, ensure that the correct profile is selected from the ASTM Standard
Profile laboratory. Standard Profiles with only one temperature indicated
are run using calibration data obtained at -20°C. For profiles with two
temperatures indicated, the first temperature refers to the final test
temperature for the profile and the second refers to the desired calibration
temperature for that profile.
(-10°C profile using -20°C calibration data)
You will not be able to select and run ASTM profiles in cells for which
calibration data is unavailable at the specified temperature. The ASTM
profiles will not appear in the drop-down list until the number of calibra-
tions required by the method are performed.
4. Click the Run Profile button to open the Run Profile window. The
on-board CMRV microprocessor will control the temperature until
the profile has been completed. A computer connection is no longer
required until it is time to initiate viscosity/yield stress testing.
5. Select the desired End Time for the profile (this is the time you
would like to start testing) and click OK. The Start Test button will
begin blinking to indicate that profile timing has begun. The profile
will be initiated at the appropriate time.
NOTE The default End Time is the time that the temperature profile would be
completed if the profile is started immediately.
5. At the conclusion of the temperature profile you are ready to test
samples. See Chapter 11 for the test procedure.
Profile operation notes
Instrument Status window
During the profile, the Instrument View window will display the current
status of the profile, the current test temperature, the desired temperature,
time elapsed, and the time remaining until the yield stress and viscosity
