Brookfield DV2+Pro Viscometer - Manual (Page 81)

Calibration Procedure for a Small Sample 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 Small Sample
Adapter. The use of an accessory device may increase the accuracy of measurement associated
with the DV-II+Pro.
When a Small Sample Adapter is used, the water jacket is connected to the water bath and the
water is stabilized at the proper temperature:
1) Put the proper amount of viscosity standard fluid into the sample chamber. The amount varies
with each spindle/chamber combination. (Refer to the Small Sample Adapter instruction
manual).
2) Place the sample chamber into the water jacket.
3) 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 DV-II+Pro.
4) Allow 30 minutes for the viscosity standard, sample chamber and spindle to reach test temperature.
5) Measure the viscosity and record the Viscometer reading.
Note: The spindle must rotate at
least five (5) times before readings are taken.
Calibration Procedure for a Thermosel System
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 Thermosel.
The use of an accessory device may increase the accuracy of measurement associated with the
DV-II+Pro.
When a Thermosel System is used, the controller stabilizes the Thermo Container at the test
temperature.
1) Put the proper amount of HT viscosity standard fluid into the HT-2 sample chamber. The
amount varies with the spindle used. (Refer to the Thermosel instruction manual).
2) Place the sample chamber into the Thermo Container.
3) 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 DV-II+Pro.
4) Allow 30 minutes for the viscosity standard, sample chamber and spindle to reach test temperature.
5) 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 UL or DIN Adapters
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 UL or DIN
Adapters. The use of an accessory device may increase the accuracy of measurement associated
with the DV-II+Pro.
