5.9. SETUP – DIAG: DIAGNOSTICS FUNCTIONS
The SETUP>MORE>DIAG menu provides a series of diagnostic functions whose
parameters are dependent on firmware revision (refer to Menu Tree, A-5, in Appendix
A). Table 5-3 describes the functions and provides a cross-refe
rence 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.

SECTION
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
5.9.1
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
5.9.2
ANALOG I/O CONFIGURATION: Analog input/output
parameters are available for viewing and configuration.
DIAG AIO
5.9.3
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.
DIAG OPTIC
5.9.4
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.
DIAG ELEC
5.9.5
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
2
concentration
DIAG LAMP
5.9.6
PRESSURE CALIBRATION: The analyzer records the current
output of the sample gas pressure sensor. This value is used
by the CPU to compensate the SO
2
concentration when the
TPC feature is enabled.
DIAG PCAL
5.9.7
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
5.9.8
TEST CHAN OUTPUT: Configures the A4 analog output
channel.
DIAG TCHN
