Brookfield DV-II+ Digital Viscometer - Manual (Page 18)

3. At this point, the user need only press the MOTOR ON/OFF key to begin the timed torque
operation. Any other key will abort the process and he will have to begin again by simultaneously
pressing the SET SPEED and SELECT SPINDLE keys.
4. We will assume that the user pressed the MOTOR ON/OFF key to ON and is now presented with
the following display for the duration of the timed torque run:
Figure 31
Note:
1. When this mode has begun, a press of the MOTOR ON/OFF key will interrupt the time
to torque operation and return the user to normal operation.
2. Also, see Comments on Print Mode Operation in Section II.10.4 for a description of
print options available on DV-II+ during the Time to Torque run.
The seconds display will increment from zero (0) to 59 in one (1) second intervals and the current
value of the viscometer torque will be updated continuously. When seconds reach 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:
Figure 32
At this point, the viscometer will stop the motor and continue to display this screen until the user
presses the UP or DOWN arrow keys or the PRINT key to view the viscosity that was current
at the Timed Torque completion. The display would appear as follows:
Figure 33
The display will switch between that of Figures 32 and 33 for each press of either the UP or
DOWN arrow key. Pressing any key except the UP or DOWN arrow key or the PRINT key will
cause the viscometer to exit the Timed Torque mode and resume normal operation.
Note:
1. The user can press the PRINT key while in either of these two screens (Figures 32 and 33)
to send one standard print string to the attached printer as many times as the user presses
the PRINT key. Pressing any other key will exit this mode and return the viscometer to
normal operation.
2. For the Time to Torque method, the DV-II+ Viscometer will retain the last entered torque
in EEPROM for use when the user elects to perform a time to torque test again.
