8.
Close the lid on the pressure vessel. Insert the thermocouple, but do not
tighten thermocouple fitting.
9.
Press the FILL button and fill the pressure vessel with oil. With a paper
towel and the supplied 5/8” wrench, wait for all the air to escape the
thermocouple hole and oil to begin seeping out. Once oil is seen, fully
tighten the thermocouple fitting.
10.
Turn off cooling if active. Verify the instrument is reading consistency and
press Start Test.
10.2 Example of Stopping a Thickening Time Test
The steps listed below are for experienced users who are familiar with
consistometer operation.
1.
There is a selection available for automatic or manual shutdown. In
automatic shutdown, the type of shutdown may be chosen. Automatic
shutdown is achieved by either selecting a maximum consistency or elapsed
time value in the live testing screen or waiting for that value to be reached.
It takes 60 seconds after the value has been reached for the control software
to perform shutdown. To manually stop a test, press Stop Test.
2.
If manually shut down and the temperature is above ambient, press Cool in
the main screen. If automatic shutdown has been activated cooling will
activate automatically.
3.
Turn the pump off by pressing the Pump On/Off button.
4.
Select Drain Cylinder from the drop down box and wait for the pressure to
be released from the pressure vessel.
5.
Wait for the cylinder to cool enough to touch and then slowly loosen the
thermocouple using a shop towel to prevent any residual pressure spray
from going everywhere.
6.
Take care to observe the temperature of the various components as they will
be hot after a test. When the cylinder is cool enough to touch, remove the
top plug from the pressure vessel.
7.
Using the supplied slurry cup and potentiometer bails remove the
potentiometer and slurry cup. Take care to drain any leftover oil from the
tops back into the cell.
8.
Disassemble the slurry cup and remove the slurry before it sets and
becomes too hard.
