high-pressure filter on the autoclave assembly.
6. Disconnect the top sensor cable.
7. Disconnect the bottom sensor cable from the front panel.
8. Remove the thermocouple or disconnect the cable.
9. Lift the test cell from the autoclave assembly. Guide the bottom transducer
cable through the front panel of the instrument.
Cleaning the Test Cell
When the test cell has been cooled and removed from the autoclave, it should be
cleaned according the following guidelines.
1. Place the test cell in a vice, topside up. Use the wrench flats and do not
scratch or nick the cylinder or plugs.
2. Remove the top plug and pour off any standing water on the cement sample.
3. Remove the cell from the vice and replace in the vice topside down.
4. Unscrew and remove the bottom plug of the test cell.
5. Turn the cell over and drive the cement sample out of the test cell with a
hammer.
6. Clean the cement and grease from the top and bottom plugs and cylinder with
solvent.
7. When all traces of cement have been removed, grease the inner surfaces of the
test cell, including the seal and O-rings.
8. Replace the O-rings if they were damaged during the test.
9. The instrument is now ready to run another test.
