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: Analog input/output parameters are
available for viewing and configuration.
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.
LAMP CALIBRATION: The analyzer records the current voltage output
of the UV source reference detector. This value is used by the CPU to
calculate the lamp ration used in determining the H
(see 10.2.2)
PRESSURE CALIBRATION: The analyzer records the current output of
the sample gas pressure sensor. This value is used by the CPU to
compensate the H S concentration when the TPC feature is enabled.

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.
TEST CHAN OUTPUT: Configures the A4 analog output channel.
A series of diagnostic tools is grouped together under the SETUPMOREDIAG
menu. As these parameters are dependent on firmware revision (see Menu Tree A-5 in
Appendix A). The individual parameters, however, are explained in more detail in the
following section, indicated in Table 4-8. 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.
