6.6.SETUP Æ MORE Æ DIAG: USING THE DIAGNOSTICS FUNCTIONS

The information found in Section 6.13 of the M300E/EM Operators Manual (P/N 04288) is applicable to the M300EU with the following exception(s):

•There is no DISPLAY SEQUENCE CONFIGURATION submenu available under the DIAG menu of the M300EU.

•The following table supersedes Table 6-15 of the M300E/EM Operators Manual (P/N 04288).

Table 6-4:	M300EU Diagnostic (DIAG) Submenus
DIAGNOSTIC FUNCTION AND MEANING		Front Panel
		Mode Indicator
SIGNAL I/O: Allows observation of all digital and analog signals in the		DIAG I/O	See
instrument. Allows certain digital signals such as valves and heaters			M300E/EM
to be toggled ON and OFF.			Manual
ANALOG OUTPUT: When entered, the analyzer performs an analog		DIAG AOUT	See
output step test. This can be used to calibrate a chart recorder or to			M300E/EM
test the analog output accuracy.			Manual
ANALOG I/O CONFIGURATION: This submenu allows the user to
configure the analyzer’s four analog output channels, including
choosing what parameter will be output on each channel. Instructions		DIAG AIO	6.7.1
that appear here allow adjustment and calibration the voltage signals
associated with each output as well as calibration of the analog to
digital converter circuitry on the motherboard.
ELECTRIC TEST: The analyzer is performing an electric test. This test		DIAG OPTIC	See
simulates IR detector signal in a known manner so that the proper			M300E/EM
functioning of the sync/demod board can be verified.			Manual
DARK CALIBRATION: The analyzer is performing a dark calibration		DIAG ELEC	See
procedure. This procedure measures and stores the inherent dc			M300E/EM
offset of the sync/demod board electronics.			Manual
PRESSURE CALIBRATION: The analyzer records the current output		DIAG PCAL	See
of the sample gas pressure sensor. This value is used by the CPU to			M300E/EM
compensate the CO concentration.			Manual
FLOW CALIBRATION: This function is used to calibrate the gas flow		DIAG FCAL	See
output signals of sample gas and ozone supply. These settings are			M300E/EM
retained when exiting DIAG.			Manual
