We will assume that the user pressed the ENTER/AUTORANGE key. You will now be presented
with a screen similar to Figure III-25 for the duration of the timed torque run:
TORQUE = 24.2%
MIN: 15 SEC: 13
Figure III-25
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
III-13.
The seconds display will increment from zero (0) to fty-nine (59) in one (1) second intervals
and the current value of the viscometer torque will be updated continuously. When seconds
reaches fty-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 III-26
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 III-27
The display will switch between that of Figures III-26 and III-27 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 III-22 displayed awaiting another Timed Torque run.
The user can press the PRINT key while in either of these two screens (Figures III-26 and III-27)
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+Pro 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.
