(cP or mPa•s).

LVDV-II+Pro Viscometers are provided with a set of four spindles
and a narrow guardleg; RVDV-II+Pro Viscometers come with
a set of six spindles and a wider guardleg; HADV-II+Pro and
HBDV-II+Pro Viscometers come with a set of six spindles and no
guardleg. (See Appendix F for more information on the guardleg.)
The spindles are attached to the viscometer by screwing them
onto the coupling nut on the lower shaft, see Figure II-6. Note
that the spindles have a left-hand thread. The lower shaft should
be secured and slightly lifted with one hand while screwing the
spindle to the left. The face of the spindle nut and the matching
surface on the lower shaft should be smooth and clean to prevent
eccentric rotation of the spindle. Spindles can be identified by the
number on the side of the spindle coupling nut.
The motor should be OFF whenever
spindles are being removed or attached.
If your instrument has the EZ-Lock system, the spindles are
attached as follows:
With one hand hold the spindle, while gently raising the spring-
loaded outer sleeve to its highest position with the other hand, as
shown in Figure II-7. Insert the EZ-Lock Spindle Coupling so that
the bottom of the coupling is flush with the bottom of the shaft,
and lower the sleeve. The sleeve should easily slide back down
to hold the spindle/coupling assembly in place for use. [Spindles
can be identified by entry code; look for the number on the side
of the EZ-Lock spindle coupling.]
The motor should be OFF whenever
spindles are being removed or attached.
Note: Keep the EZ-Lock Spindle Coupling and
outer sleeve as clean as possible and free
from debris that could become lodged
inside the adapter.
The DV-II+Pro must have a Spindle Entry Code number to calculate
Viscosity, Shear Rate and Shear Stress values. The DV-II+Pro
memory contains parameters for all standard Brookfield spindles
including custom spindles and the two digit entry code for each
spindle (the complete list of entry codes may be found in Appendix
D).
