TIMED TORQUE
SET TORQUE: 00%
Figure II-22
Using the UP and DOWN ARROW keys, the user enters a value for the torque level which
the viscometer must achieve. This value can be as high as 99%.
NOTE: The value for torque must be other than zero or you will not be able
to exit this mode.
2. The user presses the SELECT SPINDLE key one more time to end the torque input at which
point the viscometer will display the following screen:
TIMED TORQ:PRESS
MOTOR ON OFF
/
Figure II-23
The time to torque value can be as high as 99 minutes and 59 seconds.
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 the user 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:
TORQUE = 24.2%
MIN: 15 SEC: 13
Figure II-24
NOTE: 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.
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:
22M 54S TO 85%
TIMED TORQ DONE
Figure II-25
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 to view the viscosity that was current at the
Timed Torque completion. The display would appear as follows:
