V. DVLOADER SOFTWARE
The DVLOADER software is a WINDOWS-based program provided on a CD which comes with the
Programmable DV-II+Pro Viscometer.
V.1 B.E.V.I.S. Overview
DVLOADER utilizes B.E.V.I.S. (Brookfield Engineering Viscometer Instruction Set), a scripting
language that allows for the creation of programs to control the Programmable DV-II+Pro
Viscometer. Programs are created on a PC, then loaded into the viscometer using the DVLoader
software. Some testing capabilities that are possible include the following:
• Repeatedly run the same test program for quality control purposes.
• Wait for a specific condition before continuing with the test (i.e. a torque value, a temperature
value, a key press, etc.).
• Run the viscometer at any of the speeds in the Custom Speed menu.
• Display messages to the screen or an attached printer to aid the operator.
• An internal clock that keeps time between each printed data line (this time is displayed as the
last parameter on each printed line). This provides a consistent time base for the collected
data.
V.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 specified 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+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 specified 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 specified. MM:SS is minutes:seconds.
