Stopping the Test
1.
When the test has finished all of the programmed steps or has met the
specified end conditions, the system will automatically turn off the heat
and turn on the cooling. If the cell temperature is over 190°F (87.8°C), the
unit will maintain the required 1,000 psi (6.9 MPa) to prevent the sample
from boiling. Once the cell temperature is below 190°F (87.8°C), the cell
pressure will vent completely.
2. When the cell has cooled completely, turn the “HEAT”, “COOL”, and
“PRESSURE” switches off.
3. Turn the Water Supply valve to “DRAIN”.
4. Unscrew and remove the high-pressure supply line from the cell cap and
the instrument cabinet.
5. Unplug the thermocouple and transducer.
6. Lift the cell out of the heating jacket.
When removing the test cell, pay special attention to the transducer and
make sure it doesn’t pull off the end of the transducer cable with the cell.
Use caution. The test cell may contain a small amount of air at high
temperature and / or pressure.
