6.2.2. Warning Messages
The most common instrument failures will be reported as a warning on the analyzer’s front
panel and through the COM ports. Section 11.1 explains how to use these messages to
troubleshoot problems. Section 3.5.3 shows how to view and clear warning messages.
Table 0-3 lists all warning messages of firmware C.4.

Message Meaning
ANALOG CAL
WARNING
The instruments analog-to-digital converter (A/D) circuitry or one of the
analog outputs are not calibrated.
AZERO WRN XXX.X MV
The reading taken during the Auto-zero cycle is outside the specified limits.
The value shown here as “XXX.X” indicates the actual auto-zero reading at
the time of the warning.
BOX TEMP WARNING The temperature inside the M200E chassis is outside the specified limits.
CANNOT DYN SPAN Remote span calibration failed while the dynamic span feature was ON.
CANNOT DYN ZERO Remote zero calibration failed while the dynamic zero feature was ON.
CONFIG INITIALIZED Configuration storage was reset to factory configuration or was erased.
CONV TEMP WARNING NO
2
converter temperature is outside of specified limits.
DATA INITIALIZED iDAS data storage was erased.
HVPS WARNING High voltage power supply for the PMT is outside of specified limits.
IZS TEMP WARNING
On units with IZS option installed: The IZS temperature is outside of
specified limits.
OZONE FLOW
WARNING Ozone flow is outside of specified limits.
OZONE GEN OFF
Ozone generator is off. This is the only warning message that automatically
clears itself when the ozone generator is turned on.
PMT TEMP WARNING PMT temperature is outside of specified limits.
RCELL PRESS WARN Reaction cell pressure is outside of specified limits.
RCELL TEMP WARNING Reaction cell temperature is outside of specified limits.
REAR BOARD NOT DET The firmware is unable to communicate with the motherboard.
RELAY BOARD WARN
The firmware is unable to communicate with the relay board.
SAMPLE FLOW WARN The flow rate of the sample gas is outside the specified limits.
SYSTEM RESET The computer rebooted or was powered up.
6.2.3. Calibration Functions
Pressing the CAL key switches the M9110EH into calibration mode. In this mode, the user can
calibrate the instrument with the use of calibrated zero or span gases.
If the instrument includes either the zero/span valve option or IZS option, the display will
also include CALZ and CALS keys. Pressing either of these keys also puts the instrument
into multipoint calibration mode.
The CALZ key is used to initiate a calibration of the zero point.
The CALS key is used to calibrate the span point of the analyzer. It is recommended that
this span calibration is about 80-90% of full scale of the analyzer’s operating range.
