Brookfield DV2+Pro Viscometer - Manual (Page 15)

Brookfield Engineering Labs., Inc. Page 15 Manual No. M03-165-F0612
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 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 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.
Note: The number 99 spindle is for use with special spindles when using
Brookfield’s Rheocalc computer program. Refer to the Rheocalc operator
manual for further information on using “99” spindles.
The DV-II+Pro may also be programmed at Brookfield Engineering for “special” user spindles.
These “special” spindles will appear on the spindle scroll list starting with designation “AA”
and continuing through “AZ”. Contact Brookfield Engineering regarding your needs for special
spindles.
II.3 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 configured 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
