MIN: 15 SEC: 13

Figure IV-20

Note:

When this mode has begun, a press of the MOTOR ON/OFF/ESCAPE key will

cancel the Timed Stop sequence and return the user to the screen of Figure IV-14.

Also note that data will be displayed in the currently selected method i.e. CGS

or SI units. Pressing the SELECT DISPLAY key allows display of alternate

data values such as Shear Stress, Shear Rate or Torque.

The seconds display will decrement from fifty-nine (59) to zero (0) in one (1) second intervals.

When seconds reaches zero (0), the minutes value will decrement by one (1) minute. This will

continue until all of the time has elapsed at which point the viscometer will display the following

screen:

cP 123e6
TIMED STOP DONE

Figure IV-21

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

except the

DOWN ARROW

key, the

key or the

SELECT DISPLAY

key, is pressed. The user

can, while this display is current, press the

DOWN ARROW

keys to view the torque and speed

that were current at the time the display was frozen. The display would appear as follows:

%=76.4 RPM=100
TIMED STOP DONE

Figure IV-22

The display will switch between that of Figures IV-21 and IV-22 for each press of the

DOWN

arrow keys. A press of the

screen would send one standard print line to the attached printer

for each press of the

key. Pressing any key (except the

DOWN ARROW

keys, the

key or the

SELECT DISPLAY

key) will cause the viscometer to return to the Timed Stop Start Screen

of Figure IV-19 displayed awaiting another Timed Stop run.

Note: To run multiple timed stop tests, the user needs to press ENTER twice from the screen

shown as Figure IV-22.

The user can press the

key while in either of these two screens (Figures IV-21 and IV-22) to

send one standard print string to the attached printer as many times as the user presses the

key.

In addition, the

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.
