That done, the user is presented with the following screen:

TIMED STOP

ENTER TO START

Figure 40

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 36 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

the following screen for the duration of the timed run:

cP 123.5e6

MIN: 15 SEC: 13

Figure 41

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 36.

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 42

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

except the UP or DOWN ARROW key, the PRINT key or the SELECT DISPLAY key is pressed. The user

can, while this display is current, press the UP or 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 43

The display will switch between that of Figures 42 and 43 for each press of the UP or DOWN arrow

keys. A press of the PRINT screen would send one standard print line to the attached printer for each

press of the PRINT key. As stated above, pressing any key (except the UP or DOWN ARROW keys,

the PRINT key or the SELECT DISPLAY key) will cause the viscometer to exit the Time To Stop mode

and resume operation with the screen of Figure 40 displayed awaiting another Timed Stop run.

The user can press the PRINT key while in either of these two screens (Figures 42 and 43) to send one
