• An internal clock that keeps time between each printed data line (this time is displayed as
the last parameter on each printed line) providing a consistent time base for the collected
data.
IV.3.1.1
Description of B.E.V.I.S. Commands
Command Code
Required Parameter Command Description
WTI
Time (MM:SS)
The program waits at this step until the specified time elapses.
WPT
% Torque value
The program waits at this step until the current % torque equals the
(%)
specified value.
WTP
Temperature value
The program waits at this step until the current temperature equals the
(°C)
specified value.
WKY 16 character (or less)
The specified message is displayed on the top line of the DV-III Ultra dis
text message
play while
PRESS A KEY
is displayed on the bottom line of the DV-III
Ultra. The program waits at this step until a viscometer key is pressed.
While waiting at this step, the viscometer produces a beep every few
second to remind the operator that a keypress is required to continue. If
a print interval was enabled (see SPI) at the time this command is
executed, the data print timer continues to count up. If the print interval
elapses and a key has not yet been pressed, a line of data displaying the
time since the last data print is printed as soon as a key is pressed.
SSN
Speed value
The DV-III Ultra begins rotating at the specified speed. This can be any
(RPM)
of the speeds listed in the Speed list of the DV Loader software. These
speeds are the same as those listed in the Custom Speeds list in the
viscometer’s Options menu.
SPI
Time
The DV-III Ultra begins printing data to the selected printer (serial or
(MM:SS)
parallel; as selected in the DV-III Ultra menus) at the rate specified.
MM:SS is minutes:seconds.
SSP Two digit spindle code
Calculations of viscosity, shear stress, and shear rate are performed
based on the specified spindle code. This command overrides the
spindle currently entered via the keypad on the DV-III Ultra.
STM
Temperature value
Set and control to the specified temperature if a Brookfield
Engineering Labs. temperature controller is attached to the rheometer.
STZ
N/A
Sets the data print timer clock back to zero.
PDN
N/A
The DV-III Ultra immediately prints a data string to the selected printer
(serial or parallel; as selected in the DV-III Ultra menus).
PLN 16 character (or less)
The DV-III Ultra prints the specified message to the selected printer
text message
(serial or parallel; as selec
t
ed in the DV-III+ menus).
NOTE: MM:SS is minutes:seconds
By using various combinations of the above commands, programs are created that automatically control
the viscometer and collect data (via an attached printer) from the DV-III Ultra Rheometer.
