Iii.1.3 Measurement With The Ftky3 Temperature Control Device - Ametek BROOKFIELD RST Operating Instructions Manual

and clean each piece of the sample cup separately. Do not use any object in cleaning that
might scratch the spindle or sample cup pieces.
7) Store the spindle on a soft surface or in its original container.
8) Remove the Pt100 sensor from the circulating bath and clean it. Do not use solvent on
any piece of the sensor beyond the metal rod.

III.1.3 Measurement with the FTKY3 Temperature Control Device

III.1.3.1 Standard Measuring Systems
To prepare a sample for testing in a cylinder measuring system with FTKY3 temperature control:
1) If the KE cooling device will be used, assemble it first according to the instructions in
Section I.3.6.1. The KE cooling device is required for operating temperatures beyond
the range of -10°C to +70°C in order to protect the rheometer head from damaging
temperatures.
2) Assemble the FTKY3 temperature control device as instructed in Section I.3.6.2.
3) Set the fluid circulation bath to the intended sample temperature. Do not
operate beyond temperatures of 70°C without using the KE cooling device.
Do not operate beyond the temperature range of -20°C to +180°C even with
the KE cooling device.
4) Determine the sample volume appropriate for the measuring
system to be used. (Refer to Appendix E: "Data Sheets for
Standard Measuring Systems".) Fill the sample cup with
sample material accordingly. Avoid trapping air bubbles in
the sample material, as they may result in irreproducible
or false data. Be sure to use a sample cup designed for use
with the FTKY3.
5) Carefully insert the spindle into the sample cup. Avoid
introducing air bubbles to the sample. Figure III-7 shows
how the measuring system should look so far.
6) Ensure that the spindle coupling is open. If it is closed, open
the spindle coupling by lifting the black coupling sleeve
up. The inner ring of the coupling will be visible under the
coupling sleeve. Figure III-3 shows an open spindle coupling.
7) Remove the threaded ring for securing the sample cup from
the FTKY3 device.
8) Insert the sample cup into the water jacket from below and
reattach the threaded ring to secure the sample cup in place.
Be careful to align the spindle shaft with the coupling. Figure
III-4 shows a closed spindle coupling.
9) Reattach the threaded ring to the instrument to secure the sample cup in place.
10) Insert the spindle into the coupling. Be careful to insert the spindle shaft into the coupling
without bumping against it. Close the coupling by sliding the coupling sleeve down.
11) If using the KE cooling device, begin cool water circulation through the device.
12) Begin circulation to the FTKY3 water jacket. Wait for the sample to come to temperature.
13) Proceed with measurement.
To disassemble a cylinder measuring system used with the FTKY3 temperature control device:
1) Take note of the operating temperature. Allow the measuring system to cool to a safe
temperature before disassembling.
2) Release the spindle by opening the spindle coupling.
