The SYSTEM FAULTS display provides a start, pass or fail indication for various
parameters which are continually monitored. These parameters must be within
acceptable operating ranges in order to display PASS. If the instrument is in startup
mode, START will be displayed. For further information on the SYSTEM FAULTS
screen, refer to the EC9830 Service Manual.
2.6 Analog Output
Analog output connections are described in section 2.1.2.1.
Before setting up the recorder and DAS analog outputs, decide what offset and
over-ranging choices to make. A brief explanation of these terms follows, then the
setup procedure is given. The analog output and over-range settings have no
impact on the measurement range of the analyzer, but only affect the analog
output scaling.
