The OPTION/TAB key is used for moving from input field to input field and the ENTER key to accept
the current input for a step. On entry to this screen, the underscore cursor would be flashing (as
shown) under the first digit of the step RPM. Use the numeric keys to make changes to the step speed,
repeating the input as many times as required until satisfied.
When satisfied with the speed input, press the OPTION/TAB key which moves the flashing cursor
down to the first character of the time field. The same procedure is used here to input the step time
as was used to enter the RPM above. Speed or time data that is out of range, as defined by Table
1, will result in the following screen:
Figure 24
This screen will be displayed for 1-3 seconds.
When ready, the user may press the PROG RUN key to display the data for the next step in the
program, or the MOTOR ON/OFF/ESCAPE key (whereby none of the changes up to that point will be
accepted) to return to the screen of Figure 22. To end a program, the user simply enters and accepts
a step RPM and Time of zero (0) or continues to input step data until the program reaches the twenty-
five (25) step program limit. In either case, the following screen will be displayed:
Figure 25
To use the currently selected speed set, press the “3” key in Figure 25. This would immediately
revert to the default screen modified as follows:
Figure 26
Note: If at this point, prior to using the program the user wished to enter a direct speed, a
press of any numeric key which would result in a display similar to Figure 15. At
the completion of the direct speed input, the display would revert to Figure 26 above
with the appropriate RPM displayed, and the viscometer running at that speed.
