8. Cold Bath. For performing Sequence I and III
test procedures.
9. Hot Bath. For performing Sequence II test
procedures.
4.2 Flowmeter Setup and Operation
1. Connect the inlet on the flowmeter manifold
fitting to a source of clean dry air. Instrument
grade compressed air is recommended for this
application. Tygon or heavy wall rubber tubing
is suitable for connection to the manifold.
2. Adjust the inlet air pressure to the regulator to
fifteen (15) psi for normal operation.
3. Connect the outlets on the flowmeters to the
air tube assemblies using new ¼” tygon
tubing.
4. Set the proper airflow by first consulting the
flowmeter calibration data in section 4.3. Find
the millimeter mark that will yield a flow of 94
ml/min.
5. Adjust the valve on the flowmeter, so that the
ball float in the tube is centered on the
millimeter value specified in the data.
6. Permit the air to flow for the duration specified
in the test procedure and disconnect the tygon
tubing from the flowmeter outlet when the
aeration period as elapsed.

4. Down Key. Used to decrease the set
point temperature and to decrease or
change
parameter values when
programming the temperature controller.
5. Up Key. Used to increase the set point
temperature and to increase or change
parameter values when programming the
temperature controller.
6. Exit / Function Key. This key is used to
exit or leave a level. One level backward
