USING PROGRAMMED SPEEDS WITH A ZERO TIME INTERVAL
Assume the following:
A speed set has been selected.
A subset of the speed set has not been selected. (i.e. we will use the entire set of speeds)
The speed set included a time interval that was equal to zero minutes and zero 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:
Figure 39
Or, if the user had selected the LOCKOUT option, the default screen above would appear as in
Figure 40 below:
Figure 40
Here, the LOCKOUT mode is indicated by the revision to the top line of Figure 40 where
SPINDLE has been contracted to “SPDL” and the two-letter combo: “LK” is being used to
indicate the “LOCKOUT condition. Please note that while TORQUE is presently being
displayed, there is nothing to prevent the user from pressing the SELECT DISP key to change the
data display item.
The item to note here is the message being displayed on line 3 informing the user that the program
is at speed #02 of the 12 speeds comprising speed set #02. The DV-III+ will continue to operate
at 112 RPM until the ENTER key is pressed. At that point (pressing the ENTER key), two distinct
events will occur:
1. The DV-III+ will ramp up (or down) to programmed speed #03 and,
2. Since the printer is On (PRTN), the data corresponding to the last speed (112 RPM) that existed
at the time the ENTER key was pressed will be sent to the attached printer.
Thus, if 12 speeds comprised the selected speed set, then the user would be required to press the
ENTER key 12 times to exercise the entire speed set. After the last speed has been executed (i.e.
the user pressed the ENTER key for the twelfth time), the viscometer speed will be set at ZERO RPM
and the following message will be displayed:
