4.13. SETUP MORE DIAG: USING THE DIAGNOSTICS
FUNCTIONS
A series of diagnostic tools is grouped together under the
SETUPMOREDIAG menu. As these parameters are dependent on
firmware revision (see Menu Tree A-6 in Appendix A). The individual
parameters, however, are explained in more detail in the indicated in 6-15. These
tools can be used in a variety of troubleshooting and diagnostic procedures and
are referred to in many places of the maintenance and trouble-shooting s.

DIAGNOSTIC FUNCTION AND MEANING
Front Panel
Mode Indicator
SECTION
SIGNAL I/O: Allows observation of all digital and analog signals in
the instrument. Allows certain digital signals such as valves and
heaters to be toggled ON and OFF.
DIAG I/O
4.13.2
ANALOG OUTPUT: When entered, the analyzer performs an analog
output step test. This can be used to calibrate a chart recorder or
to test the analog output accuracy.
DIAG AOUT
4.13.3
ANALOG I/O CONFIGURATION: the signal levels of the instruments
analog outputs may be calibrated (either individually or as a
group). Various electronic parameters such as signal span, and
offset are available for viewing and configuration.
DIAG AIO
4.13.4
ELECTRIC TEST: The analyzer is performing an electric test. This
test simulates IR detector signal in a known manner so that the
proper functioning of the sync/demod board can be verified.
DIAG OPTIC
4.13.5
DARK CALIBRATION: The analyzer is performing a dark
calibration procedure. This procedure measures and stores the
inherent dc offset of the sync/demod board electronics.
DIAG ELEC
4.13.6
PRESSURE CALIBRATION: The analyzer records the current
output of the sample gas pressure sensor. This value is used by
the CPU to compensate the CO
2
concentration.
DIAG PCAL
4.13.7
FLOW CALIBRATION: This function is used to calibrate the gas flow
output signal. This setting is retained when exiting
DIAG.
DIAG FCAL
4.13.8
TEST CHAN OUTPUT: Configures the A4 analog output channel.
