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).

DIAGNOSTIC FUNCTION AND MEANING
Front Panel
Mode Indicator
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
See
M300E/EM
Manual
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
See
M300E/EM
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
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.
DIAG AIO
6.7.1
ELECTRIC TEST: The analyzer is performing an electric test. This test
simulates IR detector signal in a known manner so that the proper
functioning of the sync/demod board can be verified.
DIAG OPTIC
See
M300E/EM
Manual
DARK CALIBRATION: The analyzer is performing a dark calibration
procedure. This procedure measures and stores the inherent dc
offset of the sync/demod board electronics.
DIAG ELEC
See
M300E/EM
Manual
PRESSURE CALIBRATION: The analyzer records the current output
of the sample gas pressure sensor. This value is used by the CPU to
compensate the CO concentration.
DIAG PCAL
See
M300E/EM
Manual
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.
