Operation
Completing the Test
When the slurry consistency reaches the maximum consistency set in the
options (see page 36), the heater, motor, and pump will automatically turn
off and the cooling system will turn on. The red light on the Status Indicator
will turn on and an alarm will sound. To acknowledge the alarm, push the
Scroll Wheel.
1. Turn the HEAT, MOTOR, and DC VOLT switches off.
2. If the Chart Recorder is recording the test, open the door and push the
“REC” button to stop it.
3. Wait for the cell to cool. When the cell has cooled, turn off the
PUMP switch and slowly open the Pressure Release valve.
Never release pressure while the temperature is above 190°F.
If the pump switch is in the automatic position, the consistometer will
maintain pressure above 5,000 PSI as long as the temperature above
190°F.
Always release the pressure very slowly to avoid pulling cement into the
plumbing.
4. Turn the CYLINDER switch to DRAIN and turn the AIR TO CYLINDER
switch on. This will allow air into the test cell and force the oil back into
the reservoir.
5. When you hear air venting from the Consistometer, turn off the
AIR TO CYLINDER switch.
6. Remove the thermocouple from the cell cap.
7. Unscrew the cell cap and remove it from the test cell.
8. Remove the potentiometer and the slurry cup from the test cell.
9. Turn the COOL switch off.
10. Return the cell cap to the test cell to prevent dust and other material from
entering the cell. Turn the MAIN switch off.
