DIAGNOSTIC FUNCTION AND MEANING
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.
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.
ANALOG I/O CONFIGURATION: This submenu allows the user to configure
the analyzer's four analog output channels, including choosing what parameter
will be output on each channel. Instructions that appear here allow adjustment
and calibration the voltage signals associated with each output as well as
calibration of the analog to digital converter circuitry on the motherboard.
DISPLAY SEQUENCE CONFIGURATION: Allows the user to program which
concentration values are displayed in the .
OPTIC TEST: When activated, the analyzer performs an optic test, which turns
on an LED located inside the sensor module near the PMT (Fig. 10-15). This
diagnostic tests the response of the PMT without having to supply span gas.
ELECTRICAL TEST: When activated, the analyzer performs an electric test,
which generates a current intended to simulate the PMT output to verify the
signal handling and conditioning of the PMT preamp board.
OZONE GEN OVERRIDE: Allows the user to manually turn the O
or off. This setting is retained when exiting DIAG. During initial power up TMR
(timer) is displayed while the Ozone brick remains off for the first 30 minutes.
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.

A series of diagnostic tools is grouped together under the SETUP-MORE-DIAG menu.
These parameters are dependent on firmware revision. 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 sections.
An overview of the entire DIAG menu can be found in menu tree A-6 of Appendix A.1.
