Brookfield CAP1000 Viscometer - Manual (Page 25)

Brookfield Engineering Labs., Inc. Page 23 Manual No. M02-32A0607
Notes: a. Lower the handle gently. DO NOT FORCE THE CONE ONTO THE
PLATE.
b. The sample must completely cover the face of the cone and extend beyond the
edge of the cone about 1.0 mm.
c. Release the solvent trap placing it onto the plate over the cone so it does not
touch the cone shaft.
The user should ensure that the substances placed under test do not release poisonous,
toxic or flammable gases at the temperatures to which they are subjected to during the
testing.
7. Allow the cone, plate and sample to equilibrate to the temperature control setting.
Note: A minimum of one (1) to three (3) minutes equilibrium time is recommended, de-
pending upon the sample.
8. Set the Run Time for rotating the cone (Section II.6) and the Hold Time.
9. Put the printer on-line (optional, Section II.7).
10. Press the
RUN key and execute the viscosity measurement.
Note: Due to the dynamics of shearing a fluid in the CAP “H” series Viscometers, the
temperature display may indicate a deflection from the equilibrium temperature
setting as the cone begins rotating at high shear rates. The temperature display may
indicate the temperature of the plate and the momentary changes show the cycling
of the temperature control at high temperature. The precision of the viscosity mea-
surement is maintained within the limits specified in Table 3.1.
11. Read the results of the sample test on the printer or write down the test conditions and vis-
cosity results from the viscometer display.
12. Relocate the solvent trap onto the cone adapter and raise the handle.
Caution: HOT surface.
13. It is recommended to remove the cone for cleaning. However, with care, the cone can be
cleaned in place.
Caution: HOT surface.
14. Clean the viscometer plate (refer to Section I.8).
Caution: HOT surface.
