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.(Brookeld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specic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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.

(RPM) can be any of the speeds listed in the Speed list of the

DVLoader software. These speeds are the same as those
