6.13. 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.
Table 6-15: M360E Diagnostic (DIAG) Functions
DIAGNOSTIC FUNCTION AND MEANING
Front Panel
Mode Indicator
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
6.13.2
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
6.13.3
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
6.13.4
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
6.13.5
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
6.13.6
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
6.13.7
FLOW CALIBRATION: This function is used to calibrate the gas flow
output signals of sample gas and ozone supply. These settings
are retained when exiting DIAG.
DIAG FCAL
6.13.8
TEST CHAN OUTPUT: Configures the A4 analog output channel.
DIAG TCHN
