Brookfield RVDV-II+Pro - II.2 Spindle Selection

Brookeld Engineering Labs., Inc. Page 13 Manual No. M/03-165-D0410
Pressing any key at this point results in the display of the DV-II+Pro default screen:
CP 0.0 20.1C
OFFRPM % 0.0

The display will vary depending upon the selection of temperature (°F or °C) and units of viscosity
(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 lower shaft. 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 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).
Note: The DV-II+Pro will remember the Spindle Entry Code which was in use when the
power was turned off.
Pressing the SELECT SPINDLE key will temporarily display the current selected spindle
code in place of temperature and cause the character S to begin to blink . It will blink for
about three seconds. If the UP or DOWN ARROW keys are pressed (while S is blinking) the
two character spindle value to the right of the S character will begin to change (in either an
increasing or decreasing direction depending upon which ARROW key is pressed) for each
press of the key. If the ARROW key is pressed and held, the display will scroll through the
spindle codes for as long as the ARROW key is depressed. When it reaches the last item in the
list (either at the top or bottom of the list) the spindle code displayed will “roll-over” to either
the rst or last spindle code and the scroll action will continue.
When the desired spindle code is displayed, release the ARROW key to halt further scrolling.
Press the SELECT SPINDLE key once again. This will cause the S character to cease blinking
and the new spindle code will be accepted for use in viscometer calculations. After 3 seconds
the current spindle code will be replaced by the temperature display.
Note: You have approximately three seconds in which to press the SELECT SPINDLE
key before the blinking stops. If you fail to press the SELECT SPINDLE key before
the blinking stops you will have to repeat the above steps and re-select the desired
spindle.
