4.8. SETUP – DIAG: USING THE DIAGNOSTICS FUNCTIONS
A series of diagnostic tools is grouped together under the SETUPMOREDIAG
menu. As these parameters are dependent on firmware revision (refer to 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.
Table 4-8: T100 Diagnostic (DIAG) Functions
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 I/O: 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 SO concentration
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 SO
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.
