TORQUE = 24.2%
MIN: 15

SEC:13

Figure II-25

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:

TORQUE = 85.0%
TIMED TORQ DONE

Figure II-26

At this point, the viscometer will stop the motor and continue to display this screen until

the user presses the

DOWN ARROW

keys to view the viscosity that was current at the

Timed Torque completion. The display would appear as follows:

22M 54S TO 85%
TIMED TORQ DONE

Figure II-27

CP 123456789
TIMED TORQ DONE

Figure II-28

The display will switch between that of Figures II-27 and II-28

for each press of either the

DOWN ARROW

key.

The test can be repeated by pressing the motor ON/OFF key.

Pressing any key except the

DOWN ARROW

key or motor ON/OFF will cause the

viscometer to exit the Timed Torque mode and resume normal operation.

The time to torque value can be as high as 99 minutes and 59 seconds.
