Insert carefully the measuring bob into the measuring bob coupling. Pay attention to insert the
measuring bob shaft into the measuring bob coupling without impact.
Move down the coupling sleeve of the measuring bob coupling (ring covered).
Fasten the measuring cup at the measuring cup mounting flange with the help of measuring cup thread.
By moving down the stand, immerse the measuring cup into the substance up to the ring mark or up to
the point where diameter of measuring cup increases.
Fig. 7.: Depth of immersion
Pay attention to the fact that any substance or solvent does not ingress into measuring bob
coupling, measuring drive or electronics.
Now the measurement can be carried out.
After the end of measurement unscrew the measuring cup thread and remove measuring cup. Then
open the measuring bob coupling and remove the measuring bob.
Clean measuring cup and measuring bob carefully. Do not use hard objects, always prevent
scratches!
Store measuring bobs on a soft pad. \
V.2 Measurement with substance in measuring system
Fill the measuring cup with substance (sample filling quantity see Appendix A1 “Data sheets of the
standard measuring system”).
Avoid air bubbles when filling in the substance as they result in non-reproducibility of the measured
values.
Place the measuring bob in measuring cup. Lift the coupling sleeve of the measuring bob coupling (ring
visible). Insert the complete measuring system from below into the measuring cup mounting flange and
screw tight using the measuring cup thread. Insert the measuring bob shaft into the measuring bob
coupling without impact. Now insert the measuring bob shaft completely into the measuring bob
coupling and move down the coupling sleeve of the measuring bob coupling (ring is covered).
In this case of measurement the substance temperature control can be carried out by immersing the
measuring system into a thermostat (delivery as special accessory). It is necessary to pay attention to
the immersion depth (Chapter 5.1).
