  • Page 14: Getting Started

    II. GETTING STARTED II.1 Power Up The DV1 Viscometer will go through a Power Up sequence when the power is turned on. The viscometer will present a blue screen for approximately 4 seconds and then the About Screen for 5 seconds. The About Screen is shown below and includes several critical parameters about the viscometer including: viscometer torque (LV, RV, HA, HB, or other), and the firmware version number.

  • Page 15: Ii.3 Navigation

    See Section I.7 for a description of Key Functions. Hot Keys are used on the DV1 Viscometer to assist with menu navigation. There are three Hot Keys located immediately under the viscometer display. The function of each key is indicated at the bottom of the display and may change depending on the screen currently in view.

  • Page 17 The DV1 requires a Spindle Entry Code number to calculate viscosity values. The two-digit code for each spindle can be found in Appendix D. Pressing the SPINDLE Hot Key on the Home screen will present the Set Spindle screen. Figure II-5 Press the Up/Down Arrow keys to scroll through the list of available spindles.

  • Page 18: Ii.6 Speed Selection

    Beginning Table II-1 NOTE: DV1 speeds are organized to conform to the historical speed sets available on the Brookfield Dial Reading viscometer. Speeds from 0.3-60 RPM are traditionally found on the LVT viscometer. Speeds from 0.5-100 RPM are traditionally found on RVT, HAT and HBT viscometers.

  • Page 19: Ii.7 Full Scale Range

    The Full Scale Range (FSR) is a calculation of the maximum viscosity value that can be measured by a spindle and speed combination when used with the specific spring torque of the DV1 Viscometer. This value represents the measured viscosity which will be displayed when the instrument’s %torque reading is at 100.

    Temperature for the Run Until Temp. end condition. For example, if the temperature probe is placed in a water bath that is set to rise to 50°C, the DV1 Viscometer may display 49.5°C when the temperature bath is at thermal equilibrium. Since the accuracy of temperature measurement is +/-1°C, this result is considered correct.

Prepare the viscometer as is described in Section III.2. Brookfield recommends that you always make cone/plate measurements with temperature control.
  • Page 35 Determine the appropriate sample volume. Refer to Table A-1 to determine the correct sample volume required for the spindle to be utilized. Select a Brookfield Viscosity Standard fluid that will give viscosity readings between 10% and 100% of Full Scale Range.

  • Page 39 Viscosity measurements should be taken under laminar flow conditions, not under turbulent flow conditions. The first consideration has to do with the accuracy of the instrument. All DV1 Viscometers have a Full Scale Range allowable error of (+/-) 1% of any spindle/speed in use. We discourage taking readings below 10% of range because the potential viscosity error of (+/-) 1% is a relatively high number compared to the instrument reading.

  • Page 47: Appendix F - Calibration Check Procedures

    • DIN Adapter • Spiral Adapter The accuracy of the DV1 is verified using viscosity standard fluids, which are available from Brookfield Engineering Laboratories or your local Brookfield agent. Viscosity standards are Newtonian, and there- fore, have the same viscosity regardless of spindle speed (or shear rate). Viscosity standards, calibrated at 25°C, are shown in Table F-1 (Silicone Oils) and Table F-2 (Mineral Oils).
  • Page 48 Brookfield Viscosity Standard Fluid - General Information We recommend that Brookfield Viscosity Standard Fluids be replaced on an annual basis, one year from date of initial use. These fluids are either pure silicone or mineral oil and are not subject to change over time.
  • Page 49 Follow theses steps using one of the recommended spindles to verify calibration of your instrument. 1) Place the viscosity standard fluid (in the proper container) into the water bath. 2) Lower the DV1 into measurement position (with guard leg if LV or RV series viscometer is used).
  • Page 50 5) Put the spindle into the test fluid and attach the extension link, coupling nut and free hanging spindle (or directly attach the solid shaft spindle) to the DV1. 6) Allow sufficient time for the viscosity standard, sample chamber and spindle to reach test temperature.
  • Page 51 1) Place the viscosity standard fluid (in the proper container) into the water bath. 2) Attach the spindle to the viscometer. Attach chamber (SA-1Y) and clamp to the viscometer. 3) Lower the DV1 into measurement position. Operate the viscometer at 50 or 60 RPM until the chamber is fully flooded.
  • Page 52 NOTE: The spindle must rotate at least five (5) times before readings are taken. Interpretation of Calibration Test Results: When verifying the calibration of the DV1, the instrument and viscosity standard fluid error must be combined to calculate the total allowable error.
  • Page 53 Any reading outside these limits may indicate a viscometer problem.

  • Page 54: Appendix G - The Brookfield Guardleg

    The current guard leg is a band of metal in the shape of the letter U with a bracket at the top that attaches to the pivot cup of a Brookfield Viscometer/Rheometer. Because it must attach to the pivot cup, the guard leg cannot be used with a Cone/Plate instrument.
  • Page 55 The guard leg is a part of the calibration check of the Brookfield LV and RV series Viscometer/Rheometer. Our customers should be aware of its existence, its purpose and the effect that it may have on data. With this knowledge, the viscometer user may make modifications to the recommended method of operation to suit their needs.
