Startup and Shutdown
Before using the 700M HFID, make sure the external plumbing and wiring have been connected
correctly as shown in the Rear Panel description. All connections (combustion air, combustion
fuel, zero gas and span gas) should be leak tight, and inlet pressure settings adjusted as
previously described. To aid flame ignition, purge the fuel line at the analyzer to remove any
residual air.
NOTE:
DO NOT energize the sample pump or introduce any sample that contains moisture until
the oven has reached an operating temperature of at least 191°C. Before Ignition is attempted,
the oven temperature should be a minimum of 120°C.
Turn on the Power switch on the analyzer’s rear panel. After the analyzer is turned on, it needs at
least 30 seconds for initialization. After a short delay, the digital display should illuminate. If the
display does not come on, check the power source and the fuse. If the problem persists, call CAI
Technical Support.
Refer to the
section and review the complete Operator’s Manual for detailed
instructions on proper setup and operation of the 700M HFID analyzer.
