RUNNING PROFILES
NOTE The guidelines in this section are not intended to supercede any test
method. Always refer to the method for validation of any test procedure.
Test preparation To run a temperature profile, first prepare the CMRV-5000 for testing
(see Chapter 6). Make sure that the POWER switch is on and that the
unit is operating normally.
Procedure 1. Place 10 ml of test oil in each of the viscometric cells to be used.
Any number of cells may be used, but all test oils for the run must be
for the same test temperature. Use a syringe or small plastic cup to
fill the cells. Ensure that the cells are seated in numerical sequence
(left to right) in the block.
2. Load the VISCPRO ® software and click Main/View Instrument.
Select the desired instrument type (MRV) and configuration from the
View Instrument window. Then click OK.
3. Record the sample ID for the first calibrated MRV cell by clicking in
the Sample ID field and typing the sample name. Then press the Tab
key to move the cursor to the next Sample ID field (or just click in
the desired ID field). Repeat the process until ID information has
been entered for all test samples.
4. (optional) Save your MRV instrument configuration by clicking
Main/Save Instrument. Select your instrument type (MRV) and
enter a name for the configuration in the Save As: field. Then click
OK to save the configuration.
NOTE You may change the Sample ID at any time prior to initiating the Yield
Stress or Viscosity tests. If you change the sample information, you may
wish to save the configuration (see step 4, above) before closing the
Instrument View window or your changes may be lost.
5. Carefully insert the rotors into their corresponding test cells, making
sure that the rotor tip at the bottom of the shaft slides into the recess
at the bottom of the cup.
CAUTION Do not drop the rotors into place or you may damage the rotor tips.
6. Secure each rotor in position with a rotor bearing pin.
Winding rotors 7. To wind the rotors in preparation for the profile, slide the pulley-
wheel assembly along the track until the pulley is aligned with the
first viscometric cell. Use the engraved lines on the slide bar as a
guide to determine the proper position of the left side of the pulley-
wheel block.
