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).

M21-400 REV.1.1
For Viscosity Standards < 30,000 cP, use a 600 mL Low Form Griffin Beaker having a working
volume of 500 mL.
For Viscosity Standards > 30,000 cP, use the fluid container. Inside Diameter: 3.25" (8.25 cm)
Height: 4.75" (12.1 cm)
Note: Container may be larger but may not be smaller.
As stated on the fluid standard label: (+/-) 0.1°C
The DVPlus should be set according to the operating instructions. The water bath must
be stabilized at test temperature. Viscometers with the letters "LV" or "RV" in the model
designation must have the guard leg attached (see Appendix F for more information on the
guard leg).
