cover (Step 9.2.6 in the ASTM D 4684-98 method and step 9.1.6 in
the ASTM D 3829 method). The tubing may be removed, along with
the cover, prior to viscosity/yield stress testing.
14. Whatever the methodology, the purge should continue throughout the
temperature profile using dry gas at a flow rate
between 20 and 30
milliliters per minute.
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 Instru-
ments 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 specifi-
cations, ensure that the correct profile is selected from the ASTM Stan-
dard 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.
