The display will vary slightly depending upon the status of the last spindle entry.

NOTE:

If the viscosity value exceeds 99,999, scientific notation is used. In FigureII-5, the
viscosity value is 123,000 cP.

II.2 Spindle Selection

LVDV-I+ Viscometers are provided with a set of four spindles and a narrow guardleg; RVDV-I+
Viscometers come with a set of six spindles and a wider guardleg; HADV-I+ and HBDV-I+
Viscometers come with a set of six spindles and no guardleg. (See Appendix E for more informa-
tion on the guardleg.)

The spindles are attached to the viscometer by screwing them on to the lower shaft. Note that the
spindles have a left-hand thread. The lower shaft should be held in one hand and lifted up. The
spindles should be screwed 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 nut.

The DV-I+ requires a Spindle Entry Code number to calculate viscosity values. The two digit
entry code for each spindle may be found in Appendix D.

NOTE:

The DV-I+ will remember the Spindle Entry Code which was in use when power
was turned off.

II.2.1 Spindle Selection for Models WITHOUT Temperature Display

Pressing the

SELECT SPINDLE

key will cause the characters on the top line of the display to

begin to blink . It will blink for about three seconds. If the

DOWN

ARROW

keys are pressed

(while

is blinking) the two character spindle value to the right of the

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 first 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

character to cease blinking and

the new spindle code will be accepted for use in viscometer calculations.
