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identied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ush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identied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Brookeld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).
