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.
