2-6 SECTION 2 – OPERATING INSTRUCTIONS
•
Screw the bottom plug into the bottom of the cylinder. It is important that the plug be
tightened so that it just contacts the top of the cylinder. Further tightening after the plug
has contacted the cylinder will not cause more effective sealing and will cause p lug
removal difficulty, as well as severe damage to the cylinder and end caps.
Preparing the Test Cell
The recommended steps in preparing the test cell and slurry for testing are outlined in the
following steps.
•
Pour approximately 200cc of cement slurry into the greased test cell. Be careful not to
get cement into the threads. If cement sets up in the threads it may make plug removal
and installation difficult.
•
Continue to pour cement into the test cell until level is 1/4 inch (6mm) below the circular
lip in the cylinder. Alternately, you can use the Slurry Level gauge provided with the
instrument. The slurry should touch the lower tab marked WET but not touch the upper
tab marked DRY. Do not overfill the test cell or cement will be forced into the pressure
and/or thermocouple ports and will plug them.
•
Pour a small amount of water into the cylinder on top of the cement--just enough to reach
the water fill line on the Slurry Level Gauge.
•
Make certain the sealing components are properly installed on the bottom plug. Apply a
liberal coating of high temperature grease on the o-ring and back-up ring.
•
Screw the top plug in place. It is important that the plug be tightened so that it just
contacts the top of the cylinder. Further tightening after the plug has contacted the
cylinder will not cause more effective sealing and will cause plug removal difficulty, as
well as severe damage to the cylinder and end caps. A small amount of water should
come out of the pressure or thermocouple port when the top plug is in place. This is very
important in that it shows that all the air has been removed from the cylinder.
•
Connect the top sensor cable to the connection labeled TOP TRANSDUCER left/right.
The transit time should be between 14.5 and 17.0 micro-sec/inch at the beginning of a test
with pressure on the cell.
•
Coat the top and bottom transducer surface with the couplant gel supplied in the
accessory kit.
•
Connect the thermocouple cable to the connector labeled “
T/C
.”
•
Install the thermocouple into the remaining high-pressure port in the top plug of the test
cell until the fitting is finger tight.
•
Slowly open the pressure valve left/right until water begins to come out the thermocouple
connection vent hole. Quickly tighten the thermocouple with a 5/8” open-end wrench. It
is recommended a rag or paper towel be placed near the thermocouple vent hole to collect
