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.
III.3.2 Time to Torque
On entry to this mode, the user is presented with the following screen display:
TIME TO TORQUE
SET TORQUE:00%
Figure 44
Using the UP or DOWN ARROW keys, the user enters a value for the torque level that you wish to
reach.
Note: The value for torque must be other than zero (0) and less than or equal
to ninety-nine (99) percent or
you will not
be able to continue.
At this point, the user presses the OPTIONS/TAB key and the screen shown in Figure 45 appears:
TIME TO TORQUE
SELECT RPM: 30
Figure 45
Using the UP or DOWN ARROW keys, the user selects a speed from the currently selected speed set.
If you had opted to use the LVRV sequential or interleaved speed sets, all those speeds would be
available by pressing the UP or DOWN ARROW keys. Conversely, if the user had selected a custom
speed set, you would be limited to those speeds comprising the custom speed set. After selecting
the speed, the user may press any one of three keys to continue: the OPTIONS/TAB key, the MOTOR
ON/OFF/ESCAPE key and the ENTER/AUTORANGE key. If the user presses the OPTIONS/TAB key
you will return to the torque input screen of Figure 44 where you may change the torque input if so
desired. Therefore, continued pressing of the OPTIONS/TAB key will toggle between the torque input
screens and the motor input screen. A press of the MOTOR ON/OFF/ESCAPE key will cancel the time
to torque operation and take the user back to the screen of Figure 35. Finally, pressing the ENTER/
AUTORANGE key will cause the DV-II+ to accept and store in EEPROM the new values (only) for
the torque level and the selected motor speed.
That done, the user is presented with the following screen:
TIME TO TORQUE
ENTER TO START
Figure 46
At this point the user must press the ENTER/AUTORANGE key to begin the timed stop operation. Any
other key press will be ignored except the MOTOR ON/OFF/ESCAPE key which will cancel the
process and take the user back to the screen of Figure 44 where you will have to begin all over again.
We will assume that the user pressed the ENTER/AUTORANGE key. You will now be presented with
