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 poison-
ous, 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 tem
-
perature 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 tem-
perature control at high temperature. The precision of the viscosity measurement 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.
III.7 Computer Control
The CAP 2000+ Viscometer can be operated remotely under PC control when using the CAP-
CALC application software.
When advanced sample analysis is required, Brookfield CAPCALC application software can
control the CAP 2000+ Viscometer from a PC. CAPCALC for Windows requires Windows
