Brookfield DV-III Ultra Rheometer - Manual (Page 37)

In which the DV-III Ultra is requesting that the user specifically press the “1” key in order to delete
the desired speed set.

Figure IV-13
Pressing the “3” key will cause the DV-III Ultra to take no action and will return the user to the
CLEAR SPEED SET opening screen, Figure IV-11. Any attempt to delete an in-use speed (“3”
for instance) will cause the DV-III Ultra to issue a “beep beep” with no action being taken. Thus
no active (i.e. selected for use) program can be deleted from this screen.
S USING PRE-PROGRAMMED SPEEDS
Pressing the three (3) key from Figure IV-2 takes the user to the speed set selection screen of Figure
IV-3 where the user selects a new speed set. That done the user is sent to the default screen with:
“SPEED SET X SELECTED” displayed on line three (3) of the screen.
The user initiates the use of programmed speeds by pressing the PROG RUN key. If the user presses
the PROG RUN
key with no speed set selected, the following error box will be displayed:
** ERROR **
A SPEED SET HAS NOT
BEEN SELECTED
PRESS ANY KEY
Figure IV-14
However, we will assume at this point that we have selected speed set #2 for use in the ensuing
data gathering operations. To initiate the use of this speed set (with finite step times or with zero
step times), the user presses the PROG RUN key and is presented with a start/end step input screen
as shown next:
SPEED SET #2
TOTAL STEPS = 13
START STEP: 01
END STEP: 13
Figure IV-15
If the user had not previously entered start and end steps, this screen will display 01 for the start
step, and the last program step (13 in this case) as the end step. The user could elect to use the entire
speed set at this point by pressing the PROG RUN
key. If the user had previously selected a start and
end step, those values would be displayed upon entry to this screen instead of the program limit
values as shown above. However, while a speed set can contain up to 25 separate speeds, the user
may be in a situation where only a few contiguous steps may be required. Therefore, this screen
allows for the option of entering the range of speeds encompassed by the start step (not necessarily
the first step) and the end step (not necessarily the last step). Pressing any numeric key at this
point will erase the currently displayed start step and substitute the new value. The user may select
a start step less than the end step ( a so-called Up Ramp) or a start step greater than the end step
( a so-called Down Ramp). Any attempt to enter a start or end speed not contained in the speed
set will result in the following display:
