IV.2 Description of B.E.V.I.S. Commands
Command Code Required Parameter Command Description
WTI Time The program waits at this step until the specied time
(MM:SS) elapses.
WPT % Torque value The program waits at this step until the current % torque
(%) equals the specied value.
WTP Temperature value The program waits at this step until the current temperature
(°C) equals the specied value.
WKY 16 character (or less) The specied message is displayed on the top line of the DV-
text message II+ display while PRESS A KEY is displayed on the bottom
line of the DV-II+Pro. The program waits at this step until a
viscometer key is pressed. While waiting at this step, the
viscometer produces a beep every few seconds 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-II+Pro begins rotating at the specied speed. This
(RPM) can be any of the speeds listed in the Speed list of the
DVLoader software. These speeds are the same as those
listed in the Custom Speeds list in the viscometer’s Options
menu.
SPI Time The DV-II+Pro begins printing data to the selected printer
(MM:SS) (serial or parallel; as selected in the DV-II+Pro menus) at the
rate specied. MM:SS is minutes:seconds.
SSP Two digit spindle code Calculations of viscosity, shear stress, and shear rate are
performed based on the specied spindle code. This
command overrides the spindle currently entered via the
keypad on the DV-II+Pro.
STZ N/A Sets the data print timer clock back to zero.
PDN N/A The DV-II+Pro immediately prints a data string to the se-
lected printer (serial or parallel; as selected in the DV-II+Pro
menus).
PLN 16 character (or less) The DV-II+Pro prints the specied message to the selected
text message printer (serial or parallel; as selected in the DV-II+Pro
menus).
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 Programmable DV-II+Pro
Viscometer.
