Pressing the ENTER key would return the user to the default screen, as depicted in Figure 40, or to
the program start and stop limit selections of Figure 34 if the PROG RUN key is pressed.
USING PROGRAMMED SPEEDS WITH A NON-ZERO TIME INTERVAL
A ssume the following:
• A speed set has been selected.
• A subset of the speed set has not been selected. (i.e. we’ll use all of the speeds in the speed set)
• The speed set included a time interval that was greater than zero (0) minutes and zero (0) seconds.
• Print mode has been set to non-continuous mode (i.e. output will be sent to the printer only when
the user presses the ENTER key).
With the above items in effect our default display screen will appear as follows after the program
steps have been completed:

The difference between this mode and the zero time interval mode is reflected in the message being
displayed on line three of the display where PROG has replaced ENTER indicating that the
program will be executed step-by-step without user intervention. Here the user is again informed
that he is at speed #02 of the 12 speeds comprising speed set #02. As the programmed time interval
elapses, the following will occur:
• The DV-III+ will ramp up (or down) to programmed speed #03 and,
• The data corresponding to the last speed (speed #02) that existed at the moment the step time
elapsed will be sent to the printer since the printer is ON (PRTN) (The automatic ramping to the
next speed will be interpreted by the DV-III+ as if the
ENTER key had been pressed, causing the
printer output).
• At the completion of the speed set, the viscometer speed will be set at ZERO RPM
After the last speed has been executed, the viscometer speed will be set at ZERO RPM and the
following message will be displayed:
