Brookfield DV-E Viscometer - Manual (Page 27)

When a Thermosel is used, the controller stabilizes the Thermo Container at the test
temperature.
1) Install the tube end cap and put the proper amount of HT viscosity standard fluid into the
HT-2 or HT-2DB 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-E.
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 a viscosity reading is taken.
Calibration Procedure for UL Adapter
When a UL Adapter is used, the water bath should be stabilized at the proper temperature:
1) Install the tube end cap and put the proper amount of viscosity standard fluid into the UL
Tube. (Refer to the UL Adapter instruction manual).
2) Attach the spindle (with extension link and coupling nut) onto the DV-E.
3) Attach the tube to the mounting channel.
4) Lower the tube into the water bath reservoir, or if using the ULA-40Y water jacket, connect
the inlet/outlets to the bath external circulating pump.
5) Allow 30 minutes for the viscosity standard, sample chamber and spindle to reach test
temperature.
6) Measure the viscosity and record the viscometer reading.
Note: The spindle must rotate at least five (5) times before a viscosity reading is taken.
Calibration Procedure for DIN Adapter Accessory
When a DIN Adapter is used, the water bath should be stabilized at the proper temperature:
1) Put the proper amount of viscosity standard fluid into the UL Tube. (Refer to the DAA
instruction manual).
2) Attach the spindle (with extension link and coupling nut) onto the DV-E.
