Brookfield DV-II+ Programmable Viscometer - Manual (Page 29)

Brookfield Engineering Labs., Inc. Page 29 Manual No. M/97-164-F1 102
a screen similar to Figure 47 for the duration of the timed torque run:
TORQUE = 24.2%
MIN: 15 SEC: 13
Figure 47
Note: When this mode has begun, a press of the MOTOR ON/OFF/ESCAPE key will
cancel the time to torque sequence and return the user to the screen of
Figure 35.
The seconds display will increment from zero(0) to fifty-nine (59) in one (1) second intervals and
the current value of the viscometer torque will be updated continuously. When seconds reaches fifty-
nine (59), the minutes value will increment by one (1) minute. This will continue until the user
selected torque value is attained at which point the viscometer will display the following screen:
22MIN 54SEC: 85%
TIMED TORQ DONE
Figure 48
At this point the viscometer will stop the motor and continue to display this screen until any key
(except the
UP or DOWN ARROW keys, the PRINT key or SELECT DISPLAY key) is pressed. The user
can, while this display is current, press the UP or DOWN ARROW keys to view the viscosity that was
current at the time the display was frozen. The display would appear as follows:
cP 123.5e6
TIMED TORQ DONE
Figure 49
The display will switch between that of Figures 48 and 49 for each press of the UP or DOWN ARROW
keys. As stated above, pressing any key (except the UP or DOWN ARROW or PRINT keys) will cause
the viscometer to exit the Time To Torque mode and resume operation with the screen of Figure 44
displayed awaiting another Timed Torque run.
The user can press the PRINT key while in either of these two screens (Figures 48 and 49) to send one
standard print string to the attached printer as many times as the user presses the PRINT key. In
addition, the PRINT key can be pressed during the actual measurement to obtain instantaneous data.
Pressing any other key will exit this mode and return the viscometer to normal operation.
Note: For both of the methods of Sections III.3.1 and III.3.2 the following apply:
1. For the Timed Stop method, the DV-II+ viscometers will retain the last value for the
time interval so that it will become the default the next time the user elects to use this
method.
2. For the Time To Torque method, the DV-II+ viscometers will retain the last entered
torque value for use when next the user elects to perform a time to torque test.
3. The user can set up a desired print interval time, then set the viscometer to the
continuous print mode and finally initiate either of the timed modes of operation.
While setting up the timed mode parameters, continuous print operation will cease.
