5.9. SETUP  DIAG: DIAGNOSTICS FUNCTIONS

A series of diagnostic tools is grouped together under the SETUPMOREDIAG menu. The parameters are dependent on firmware revision (see Appendix A). These tools can be used in a variety of troubleshooting and diagnostic procedures and are referred to in many places of the maintenance and troubleshooting sections of this manual.

The various operating modes available under the DIAG menu are:

Table 5-4: Diagnostic Mode (DIAG) Functions

DIAG SUBMENU	SUBMENU FUNCTION	Front Panel	MANUAL
		Mode Indicator	SECTION
SIGNAL I/O	Allows observation of all digital and analog signals	DIAG I/O
	in the instrument. Allows certain digital signals such		12.1.3
	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	DIAG AOUT	12.7.6.1
	chart recorder or to test the analog output accuracy.
	The signal levels of the instruments analog outputs
ANALOG I/O	may be calibrated (either individually or as a group).	DIAG AIO
	Various electronic parameters such as signal span,		5.9.2
CONFIGURATION
	and offset are available for viewing and
	configuration.
TEST CHAN	Selects one of the available test channel signals to	DIAG TCHN	5.9.4
OUTPUT	output over the A4 analog output channel.
	When activated, the analyzer performs an optic test,
OPTIC TEST	which turns on an LED located inside the sensor module	DIAG OPTIC	0
	near the PMT (Figure 13-20). This diagnostic tests the
	response of the PMT without having to supply span gas.
ELECTRICAL	When activated, the analyzer performs an electrical test,
	which generates a current intended to simulate the PMT	DIAG ELEC	0
TEST	output to verify the signal handling and conditioning of the
	PMT preamp board.
OZONE GEN	Allows the user to manually turn the O3 generator on or	DIAG OZONE	0
	off. During initial power up TMR (timer) is displayed while
OVERRIDE 1
	the Ozone brick remains off for the first 30 minutes.
FLOW	This function is used to calibrate the gas flow output	DIAG FCAL	9.7
CALIBRATION 1	signals of sample gas and ozone supply.
