Operation
Starting a Test
1. Before turning on the Consistometer, make sure the MOTOR, HEAT,
COOLING, PUMP, and FILL/DRAIN CELL switches are all off.
2. Turn the MAIN POWER switch on.
3. Turn the MOTOR switch on. This will start the motor.
4. Slowly lower the slurry cup into the test cell. When the slurry cup is
lowered all the way, the drive table will engage with the drive pins on the
bottom.
5. Lower the potentiometer into the test cell so that it sits on top of the slurry
cup. Make sure the three contacts on the potentiometer engage with the
contacts on the inside of the test cell.
The slurry cup and potentiometer both have two holes near the top for the
lift tongs (provided). Use the lift tongs to easily lower the slurry cup and
potentiometer into the test cell.
Lift Tongs
6. Turn the MOTOR switch to AUTO.
7. Carefully lower the cell cap into the test cell and tighten it.
8. Plug the thermocouple into the port near the test cell. Insert the
thermocouple into the hole in the top of the cell cap and tighten the thread
gland finger tight. Then loosen it ¼ of a turn.
9. Close the pressure release valve by turning it clockwise.
10.
Turn the FILL/DRAIN CELL switch to FILL. This will begin filling the cell
with mineral oil. When the cell is full, oil will leak out of the thermocouple
fitting on the cell cap. When this happens, tighten the fitting to seal the
cell.
