  • Page 61: Appendix E - Calibration Procedures

    APPENDIX E - CALIBRATION PROCEDURES The accuracy of the DVPlus is verified using viscosity standard fluids which are available from AMETEK Brookfield or your local authorized dealer. Viscosity standards are Newtonian, and therefore, 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 62 AMETEK Brookfield does not re-certify Viscosity Standard Fluids. We will issue duplicate copies of the Certificate of Calibration for any fluid within two years of the purchase date. AMETEK Brookfield Viscosity Standard Fluids are reusable provided they are not contaminated. Normal practice for usage in a 600 mL beaker is to return the material from the beaker back into the bottle.
  • Page 63 CALIBRATION PROCEDURE FOR A THERMOSEL SYSTEM AMETEK 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) as detailed in this Appendix. Second verify the calibration of the Viscometer using the Thermosel.
  • Page 64 Calibration Test Results). However, instrument accuracy is ±2% of the maximum viscosity range and not the standard 1%. Viscometers as shown in Table E-2. Consult with AMETEK Brookfield or an authorized dealer to determine which fluid is appropriate. INTERPRETATION OF CALIBRATION TEST RESULTS When verifying the calibration of the DVPlus, the instrument and viscosity standard fluid error must be combined to calculate the total allowable error.
  • Page 65 Example: Calculate the acceptable accuracy for viscosity measurement using DVPlus LV with SC4-21 spindle in Small Sample Adapter at 6, 12, and 30 RPM. AMETEK Brookfield viscosity standard fluid 100 cPs has an actual value of 101.5 cP at 25ºC.
