4. Re-install the battery compartment door. When the unit is first turned
on, the screen will momentarily display all LCD segments. During
this period, diagnostic tests are being conducted to ensure that the
circuits are functioning correctly. The unit will activate the audible
and visual alarms for about 1 second. The LCD will flash
continuously indicating the unit is in the unlocked position ready for

calibration.

Note: When batteries are first installed or power is lost for any reason, the analyzer
defaults to the calibration mode. All keys except the CAL and ON/OFF (I/O)
keys will be inoperable until a successful calibration is achieved.
5. Note the battery display located below the oxygen readout display. It
continuously shows a bar graph of the remaining life to the batteries.
Using new batteries will illuminate all 5 segments from the left to the
right end of the bar. The bar graph indicator is continuously on when
the analyzer is powered on.
2.1.4 Calibration
The AX300 should be calibrated before each use and every 8 hours to main-
tain accuracy.
When batteries are removed for any reason or when new batteries are in-
stalled, the oxygen analyzer defaults to the calibration mode with the LCD dis-
play flashing 00.0. Only the CAL and ON/OFF (I/O) keys are functional at this
point.
Note: For first time and for routine maintenance calibrations, make sure that the sen-
sor and sensor cable are installed correctly before attempting to calibrate the
analyzer.
