III. MAKINGVISCOSITYMEASUREMENTS

III.1 Quick Start

e DV1 Viscometer uses the same methodology for viscosity measurements as the Brookeld

Dial Reading Viscometer and the DV series of Digital Viscometers. If you have experience with

other Brookeld equipment, this section will give you the quick steps for taking a viscosity reading.

If you have not used a Brookeld Viscometer before, skip this section and go to Section III.2 for a

detailed description.

A) Assemble the Laboratory Stand. Mount and level the DV1 Viscometer (Section I.5).

B) Autozero the viscometer (Section II.2).

C) Enter the spindle number and speed of rotation using the SPINDLE and SPEED Hot Keys

functions (Sections II.5 and II.6).

D) Select the End Condition type and parameter using the OPTIONS Hot Key function

(Section II.8.1).

E) Select the Test View parameter and mode using the OPTIONS Hot Key function (Section

II.8.2).

F) Introduce the spindle into the sample and attach the spindle to the coupling nut. NOTE:

Left-handed threads.

G) Press the Motor On key to initiate test.

H) Record the test results.

I) Press the Motor On key to repeat the test. Press the HOME Hot Key to return to the Home

Screen.

III.2PreparaonsforMakingMeasurements

A) VISCOMETER: e DV1 should be turned on, leveled and autozeroed. e level is adjusted

using the two feet on the bottom of the base and conrmed using the bubble on the top

of the head. Adjust the feet until bubble is inside the center target. Set the level prior to

performing the autozero and check the level prior to each measurement.

Proper level is essential for correct operation of the DV1.

B) SAMPLE: e uid to be measured (sample) must be in a container. e standard spindles,

supplied with the DV1 (LV (1-4), RV (2-7), or HA/HB (2-7)), are designed to be used with

a 600 mL low form Grin beaker (or equivalent container with a diameter of 8.25cm).

e same applies to the optional RV1, HA/HB1 spindle. Many other spindle systems are

supplied from Brookeld with specic sample chambers such as the Small Sample Adapter,

UL Adapter and ermosel.

Brookeld recommends that you use the appropriate container for the selected spindle.

You may choose to use an alternate container for convenience; however, this may have an

eect on the measured viscosity. e DV1 is calibrated considering the specied container.

Alternate containers will provide results that are repeatable but may not be “true.”
