Quick Start Guide
Check that a temperature reading is displayed against Temperature on the display
controller as described in
Leave the analyzer operating and confirm that the temperature rises until the
analysis cell reaches the pre-set operating temperature around 50 °C (122 °F).
This takes approximately 90 minutes.
Check that a pressure reading is displayed under Pressure on the display controller.
The reading is approximately 760 Torr at atmospheric pressure.
NOTICE
A Torr is a non SI unit of pressure, defined as 1/760 of standard atmospheric pressure,
and is equal to the fluid pressure of 1 mm of mercury.
If desired, cap off the gas inlet and use an external pump to evacuate the cell.
Make sure the pressure drops as expected.
