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.

The DV-II+Pro will begin to calculate using the new spindle parameters as soon as the SELECT

SPINDLE key is pressed the second time.

SET

SPEED

Speed Selection, Setting, Running

There are 54 speeds programmed into the DV-II+Pro. These speeds correspond to the standard

LVT, RVT, HAT and HBT dial models (18 possible speeds altogether) plus 36 additional speeds.

The DV-II+Pro comes with the Sequential Speed Set already selected (see Appendix G). The

speed set will start at speed 0.0. It will then scroll up through the LV speeds, pass through speed

0.0 again, and then scroll up through the RV speeds, pass through speed 0.0 again and then repeat

the above sequence.

TheDV-II+ProcanalsobeconguredbytheoperatortointerleavetheLVandRVspeeds.See

Section IV.2.3 on Setup for a description of how to install the Interleave Speed Set.

A complete list of speed sets and custom speeds is included in Appendix G. The DV-II+Pro can be

programmed to select up to 19 of the 54 speeds for use at any one time. Speed 0.0 is automatically

included as one of the nineteen (19) speeds. See Section IV. 2.3.2 on Setup for a description of
