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 specified time

(MM:SS) elapses.

WPT % Torque value The program waits at this step until the current % torque

(%) equals the specifed value.

WTP Temperature value The program waits at this step until the current temperature

(°C) equals the specified value.

WKY 16 character (or less) The specified 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+. 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+ begins rotating at the specified speed. This can

(RPM) 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+ begins printing data to the selected printer (serial

(MM:SS) or parallel; as selected in the DV-II+ 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-II+.

STZ N/A Sets the data print timer clock back to zero.

PDN N/A The DV-II+ immediately prints a data string to the selected

printer (serial or parallel; as selected in the DV-II+ menus).

PLN 16 character (or less) The DV-II+ prints the specified message to the selected

text message printer (serial or parallel; as selected in the DV-II+ 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+

Viscometer.
