SECTION 2 – OPERATING INSTRUCTIONS
Verification of Signal Strength
You can verify the proper signal strength by running the following test:
1. Set up instrument to run a water test.
• Starting temperature: Room temperature
• Initial Pressure: 1,000 psig
2. Fill slurry cup with water.
3. Run test.
4. Initial gel value should be between 7000 – 7500.
5. If the initial gel value does not fall within these parameters, disassemble, inspect and
clean if necessary the transducer and end cap.
6. Rerun test.
Running a Test
Relief Valve Shut-off
The relief valve is only usable up to pressures of 10,000 psig. If it is necessary to
operate the autoclave at pressures above 10,000 psig, The RELIEF VALVE
SHUTOFF must be turned clockwise to the closed position.
Note: Closing the relief valve shutoff valve will also isolate the internal pressure
transducer. The pressure transducer will not measure pressures above 10,000
psig (69,050 kPa).
Pump Switch
Opens or closes a solenoid valve which controls the flow of air to the pump.
Turning this switch to the ON position causes the pump to increase pressure in the
test cell. Turning the switch to the OFF position stops the pump from operating.
Pump Water Switch
This switch is used to control the flow of water to the pump and test cell. This
switch must be OFF any time the test cell is not installed. This switch must be
ON to fill the tubing connected to the test cell with water or to operate the pump.
Coolant Switch
Used to control the flow of coolant to the heating/cooling jacket. This switch
must be OFF during a test, but should be turned ON following a test to cool the
heater and test cell.
If the optional chiller is used, the coolant switch has three settings: ON, OFF,
AUTO. The ON setting circulates chilled fluid through the heating/cooling
jacket, the OFF setting disables the heating/cooling feature, and the AUTO setting
allows the temperature controller to control the chiller. After the cool-down
segment of a temperature profile is complete, it is recommended to place the
