V.2 Measurement by Filling the Sample Cup
Fill the measuring cup with your material (see Appendix A.1 for sample volume). Avoid air
bubbles when fi lling the sample as they can affect the repeatability of the test!
Place the measuring bob into the measuring cup. Lift the coupling sleeve (the ring is visible).
Insert the complete measuring system into the measuring cup mounting fl ange from below and
screw on using the measuring cup ring. Now, insert the measuring bob shaft completely into the
measuring bob coupling and lower the coupling sleeve (the ring is covered).
If you want to measure with temperature control, the bath/circulator must be pre-set at the desired
temperature and you should wait until bath liquid and sample are at test temperature.
To remove the measuring system after the viscosity measurement has been completed, fi rst open
the measuring bob coupling and then unscrew the measuring cup thread.
When unscrewing the measuring cup, you must hold the measuring
system tightly with one hand to avoid dropping the cup and bob!
Clean the measuring cup and measuring bob carefully with a soft cloth to avoid scratches!
V.3 Measurement with Water Jacket Assembly
Install the FTKY3 jacket by removing the measuring cup ring on the rheometer (see Figure III.5).
Attach the jacket to the rheometer using the ring built onto the top of the jacket.
Connect the tubing from the bath (the bath outlet to the bottom tubing connection of the jacket;
the bath inlet to the top of the connection on the water bath) to the jacket , and connect the Pt100
on the jacket to the Pt100 socket on the back of the rheometer.
When using disposable measuring systems, insert the disposable measuring cup into the receptacle.
Fill the measuring cup with the sample. (See Appendix A.1 for sample volumes).
Avoid air bubbles when fi lling the sample as they can affect the repeatability of the test!
Place the measuring bob in the measuring cup. Lift the coupling sleeve (ring is visible). Insert the
cup and bob into the jacket from below and screw on using the measuring cup ring. Insert the bob
shaft into the measuring bob coupling and lower the coupling sleeve (ring is covered).
Set the water bath to test temperature. After the bath is at the test temperature, wait 15 minutes
to ensure that the sample, cup and bob are at test temperature.
