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
II-1, will result in the following screen:
INVALID DATA ENTRY
"BAD SPEED/TIME"
** RE-ENTER **
Figure IV-5
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 IV-3. 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:
PROGRAM #3 COMPLETE
1 = ENTER/EDIT A PGM
2 = CLEAR SPEED SET
3 = USE SPEED SET
Figure IV-6
To use the currently selected speed set, press the “3” key in Figure IV-6. This would immediately
revert to the default screen modified as follows:
RPM: 0.0 SPINDLE:
TEMP: 72.1°F PRTO
SPEED SET 3 SELECTED
TORQUE = 00.0 %
Figure IV-7
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 II-17. At the completion of the direct speed input, the
display would revert to Figure IV-7 above with the appropriate RPM
displayed, and the viscometer running at that speed.
The program is initiated by pressing the PROG RUN key. See "Using Pre-programmed Speeds."
S SPEED SETS WITH ZERO STEP TIMES
These programs when executed will require that the user press the ENTER key to progress from step
to step. On pressing the “3” key in Figure IV-3 the user is presented with the same screen that he
saw in the above description for finite step programs:
NEW SPEED SET #3
STEP 01
STEP RPM = 0.0
STEP TIME = 00:05
