Calibration Check Procedure for a Small Sample Adapter
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 uid into the sample chamber. e 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 uid and attach the extension link, coupling nut and free
hanging spindle (or directly attach the solid sha spindle) to the DVE.
4) Allow sucient time for the viscosity standard, sample chamber and spindle to reach test
temperature.
5) Measure the viscosity and record the viscometer reading; include % and cP (mPa•s).
NOTE: e spindle must rotate at least ve (5) times before readings are taken.
6) Measure viscosity and record the viscometer reading; include % and cP (mPa•s). Instrument
accuracy is ± 2% of the maximum viscosity range and not the standard 1%.
Calibration Check Procedure for a Thermosel System
A two-step process is recommended for the ermosel.
1) Evaluate the calibration of the Viscometer alone according to the procedure outlined in
the beginning of this section, entitled Calibration Procedure for LV (#61-63) and RV,
HA, HB (#1-6) Brookeld spindles.
2) Evaluate the Viscometer with the ermosel according to the procedure described below.
When a ermosel System is used, the controller stabilizes the ermo Container at the test
temperature. DO NOT USE THE THERMOSEL TO CONTROL TO TEMPERATURES
WITHIN 15° OF AMBIENT TEMPERATURES. Consult your ermosel manual for
details.
3) Put the proper amount of HT viscosity standard uid into the HT-2 sample chamber. e
amount varies with the spindle used. (Refer to the ermosel instruction manual).
4) Place the sample chamber into the ermo Container.
5) Put the spindle into the test uid and attach the extension link, coupling nut and free
hanging spindle (or directly attach the solid sha spindle) to the DVE.
6) Allow sucient time for the viscosity standard, sample chamber and spindle to reach test
temperature.
7) Measure the viscosity and record the viscometer reading; include % and cP (mPa•s).
NOTE: e spindle must rotate at least ve (5) times before readings are taken.
