5.9. SETUP – DIAG: DIAGNOSTICS FUNCTIONS
102
The SETUP>MORE>DIAG menu provides a series of diagnostic functions whose
parameters are dependent on firmware revision (refer to the menu trees in Appendix A).
Table 5-3 describes the functions and provides a cross-reference to the details for each in
the remainder of this section. These functions can be used as tools in a variety of
troubleshooting and diagnostic procedures.

Table 5-3: 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 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 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 (Section 12.7.3) is enabled (Table 5-2).
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.
