Procedure
1. Connect the heating well power cord to the appropriate power source.
Place a dial-type metal thermometer in the well in the heating jacket
and preheat to 10°F (6°C) above the desired test temperature. A pilot
light will come on when the heating jacket is at the desired temperature
as selected by the thermostat control knob.
2. Stir the sample for 10 minutes with a high speed mixer. Close both
needle valves on the test cell by turning them counter-clockwise. Invert
the cell and carefully pour the test fluid into the cell body. Leave at
least 0.5" (13 mm) of empty space below the o-ring groove to allow for
heat expansion of the fluid. Do not spill fluid on the o-ring inside the
cell.
3. Place a circle of filter paper in the groove and place an o-ring on top of
the paper. Place the cell cap into the cell, and twist it into position so
the cap locking screws will fasten to the wings of the cell cap. Evenly
tighten the set screws with the allen wrench.
