Inserting rotors
The viscometric cells are individually marked, and are calibrated with
their rotors as a matched set. For consistency, it is recommended that
cell/rotor #1 be placed in the left-most position in the block, cell/rotor #2
be placed in the adjacent position, and so forth.
1.
When you are ready to begin a temperature profile, place the visco-
metric cells in the holes in the thermostated block and inject the
required volume of sample in each. Gently place each of the num-
bered rotors into their corresponding viscometric cells.
CAUTION
Do NOT drop the rotors into position in the cell or you may damage the
rotor tips.
Inserting rotor pins
2. Align the rotor top beneath the corresponding hole in the integral
upper bearing plate.
NOTE
The upper bearing plate should have approximately 1 to 2 mm (1/32 to 1/
16 inch) clearance above the top of the rotor shaft. If the rotor tip is not
seated properly, there will not be enough clearance between the top of
the rotor shaft and the upper bearing plate to permit orientation of the
rotor under the bearing plate.
3. Insert the pin through the plate and into the center bearing hole at the
top of the rotor shafts.
NOTE
The pins, when inserted through the upper bearing plate, should extend
approximately 3 mm (1/8 inch) below the plate.
Checking rotors
4. Make sure that the rotor locking pins are in the raised (detent)
position. Rotate each of the rotors to ensure that it spins freely and
without signs of binding at either bearing.
5.
Remove the rotors from the viscometric cells.
6.
If necessary, install the pulley-wheel assembly on the slide track. See
Chapter 4 for details.
Sensor connection
7. Make sure that the free end of the sensor wire from the pulley-wheel
assembly is plugged into the receptacle marked
WHEEL
on the
CMRV-5000 front panel.
You are now ready to perform the CMRV-5000 calibration procedure or
run a test sample using the applicable test methods or a custom profile.
See the appropriate chapter for further instructions.
