When a UL or DIN UL Adapter is used, the water bath is stabilized at the proper temperature:

1) Put the proper amount of viscosity standard fluid into the UL Tube (refer to the

UL Adapter instruction manual).

2) Attach the spindle (with extension link and coupling nut) onto the DV2T.
3) Attach the tube to the mounting channel.
4) Lower the tube into the water bath reservoir, or if using the ULA-40Y water jacket,

connect the inlet/outlets to the bath external circulating pump.

5) Allow 30 minutes for the viscosity standard, sample chamber and spindle to

reach test temperature.

6) Measure the viscosity and record the Viscometer reading.

Note: The spindle must

rotate at least five (5) times before readings are taken.

Calibration Procedure using a Helipath Stand and T-Bar Spindles

When a Helipath Stand and T-Bar spindles are used:

1) Remove the T-bar spindle and select a standard LV (#1-3) or RV, HA, HB (#1-6)

spindle. Follow the procedures for LV (#1-3) and RV, HA, HB (#1-6) Brookfield

spindles outlined above.

2) T-Bar spindles should not be used for verifying calibration of the DV2T

Viscometer.

Calibration Procedure for Spiral Adapter

Brookfield recommends a two step check. First, verify the calibration of the viscometer

using the standard viscometer spindles (LV #1-3, RV #2-6, HA #2-6 and HB #2-6 or

cone/plate spindles) as detailed in this appendix. Second, verify the calibration of the

viscometer using the Spiral Adapter. The use of an accessory device may increase the

accuracy of measurement associated with the DV2T.

1) Place the viscosity standard fluid (in the proper container) into the water bath

(refer to the Spiral Adapter instruction manual).

viscometer.

3) Lower the DV2T into measurement position. Operate the viscometer at 50 or

60 RPM until the chamber is fully flooded.

4) The viscosity standard fluid, together with the spindle, should be immersed in

the bath for a minimum of 1 hour, stirring the fluid periodically (operate at 50 or

60 RPM periodically), prior to taking measurements.

5) After 1 hour, check the temperature of the viscosity standard fluid with an accurate

thermometer.

6) If the fluid is at test temperature (

C), measure the viscosity and record the viscometer reading.

Note: The spindle

must rotate at least five (5) times for one minute, whichever is greater before readings are

taken.

7) The viscosity reading should equal the cP value on the viscosity fluid standard

to within the combined accuracies of the viscometer and the standard (as

discussed in the section entitled, Interpretation of Calibration Test Results).

I. INTRODUCTION

The Brookfield DV-II Viscometer series has been the leading industrial viscometer since it

was first introduced in 1985. Brookfield has continued to develop and improve the DV-II to

provide the best value in the market for both quality control and research customers. The

Brookfield DV2T Viscometer continues in this tradition of innovation, quality and value. The

incorporation of a full color graphical touch screen display has allowed for a new and improved

user interface which preserves the single speed data collection methods while making all of

the advanced features of the DV2T readily available.
The Brookfield DV2T Viscometer measures fluid viscosity at given shear rates. Viscosity is

a measure of a fluid’s resistance to flow. You will find a detailed description of the science of

viscosity in the Brookfield publication “More Solutions to Sticky Problems”, a copy of which

was included with your DV2T.
This manual covers the DV2T Viscometer and the DV2T Extra Viscometer. The DV2T Extra is

a special package that includes several optional features to maximize the utility of the DV2T.

The DV2T Extra includes: Ball Bearing Suspension (not included in LV versions), EZ-Lock

spindle connection, Model Q Lab Stand, and RheocalcT Software. These differences are

detailed in the Components section of the manual. All references to the viscometer in this

manual will be made as DV2T. All of the optional features of the DV2T Extra may be added

individually to the DV2T Viscometer.

• The DV2T offers exceptional versatility in modes of control, allowing choice of traditional

standalone operation and automatic operation through programs downloaded from

the PC or with complete control by PC using Brookfield RheocalcT Software.

• The DV2T can be used as a traditional Brookfield viscometer for collection of single

speed viscosity data through the easy to use touch screen; just select the spindle and

speed and read the value from the display. [See Section II: Getting Started]

• The Brookfield PG Flash Software can be used to program the DV2T to control all

aspects of the test and data collection without the need for the operator to monitor

the instrument; just start the program and return to the printed test data (printer is

optional). [See Section V: PG Flash Software]

• The Brookfield RheocalcT Software will perform all control and data collection functions

of the DV2T from the PC while also providing a platform for advanced data collection
and analysis.

In any of these modes of control, the DV2T will provide the best in viscosity measurement

and control.

The principal of operation of the DV2T is to drive a spindle (which is immersed in the test fluid)

through a calibrated spring. The viscous drag of the fluid against the spindle is measured by the

Brookfield Dv2t Viscometer Manual Guide

spring deflection. Spring deflection is measured with a rotary transducer. The measurement

range of a DV2T (in centipoise or milliPascal•seconds) is determined by the rotational speed

of the spindle, the size and shape of the spindle, the container the spindle is rotating in, and

the full scale torque of the calibrated spring.
There are four basic spring torque series offered by Brookfield:
