5.1 Pre-test the Instrument
1. Arrange sample chamber (also called reservoir, cylinder, or test cell) parts for
assembly. Check all O-rings for nicks, abrasions, cement debris and brittleness.
Replace damaged O-rings.
2. Lubricate threads and O-rings with heavy grease to make cleanup easier after
testing is complete.
3. Check the filter screen for plugging or holes in the support plate.
4. Spin the paddle and shaft, listen for grinding sound, and feel for tightness. Refer
to Section 7 Troubleshooting and Maintenance for servicing, if required.
5. Screw paddle cap assembly in one end of the sample chamber and hand-tighten.
Paddle cap assembly should be as nearly flush as possible with chamber end.
6. Insert sample chamber (open end first) into the heating jacket.
7. Rotate the chamber slowly clockwise to ensure the notches engage the screws on
heating jacket end.
8. Make sure the nitrogen pressure port on the sample chamber points away from
you. If not, lift chamber slightly and rotate it a half turn, and recheck.
9. Swing locking plate into position to hold chamber in heating jacket. Use hand
knob to tighten.
10. Attach supply pressure line that is coiled on heating jacket mount to the coupling
on the side of the paddle cap assembly. Hand-tighten only.
11. To release heating jacket, pull the red knob and rotate the heating jacket 180
degrees. Pushing the knob latches the heating jacket in its new position.
12. Rotate the paddle shaft to same position as flexible drive shaft.
13. Attach flexible drive shaft into position and hand-tighten the flexible shaft collar.
