OXYGEN MONITORING SETTINGS
Identification
Name of channel: Type it, using the keyboard
Averaging
BAMOWIZ performs a measurement every 10 seconds (other frequency on request)
You can set an average of measurements during a period between 1 to 50 seconds
Set a value between 1 to 50 s
Pressure compensation
Manual pressure compensation: Select ON
Default value: OFF (manual pressure compensation is not operating)
Pressure
With ON setting, type the atmospheric pressure value (Default: 1013 hPa)
Auto (INPUT 1)
With an external pressure transmitter connected to input 1: Select ON to allow the measurement
Note: Activating this function automatically disable the manual pressure compensation.
Salinity compensation
Manual salinity compensation: Select ON
Default value: OFF (manual salinity compensation is not operating)
Salinity
With ON setting, type the salinity value (Default: 0 g/kg)
Auto (INPUT 2)
With an external salinity transmitter connected to input 2: Select ON to allow the measurement
Note: Activating this function automatically disable the manual salinity compensation.
Main display
Select the measurement unit for the main display: %, mg/l, ppm
Important:
The activation of the AUTO compensation(s) involves the use and the connection of pressure and/or salinity transmitters respectively on the
INPUTS 1 & 2. If automatic compensation is activated whithout a connected transmitter, the BAMOWIZ will show an alert by a flashing red
error message on the corresponding channel.
Note: If the dissolved oxygen probe BAMOX 453 is disconnected, BAMOWIZ will show an alert by a flashing red error message.

OXYGEN CALIBRATION
The BAMOX 453 probe is calibrated at the factory, however the user can calibrate it at any time.
The two-point calibration method (0 and 100%) is recommended for measurements of low oxygen concentrations.
IMPORTANT: Refer to the manual of the probe BAMOX 453.
Concentration 0%
In order to determine the 0 %: Immerse the probe in a solution of sulfite in water (concentration < 2 %)
Press RETURN
When the measurement stabilizes, press VALID
Note: If the offset is greater than 20%, the calibration point cannot be validated; In such a case, report to the
manual of the probe, chapters ’'Caution’’, ‘’Maintenance’’ and ‘’Replacement’’.
Then rinse the probe with clear water, and, dry it.
Concentration 100 %
The slope of the measuring scale is determined with the probe in an environment saturated of oxygen.
Position the probe end in air saturated with water vapour (for instance in a damp cloth).
Press RETURN
When the measurement stabilizes, press VALID
Note: If the gap is lower than 80 %, or greater than 120 %, the calibration point cannot be validated; In such
a case, report to the manual of the probe, chapters ’'Caution’’, ‘’Maintenance’’ and ‘’Replacement’’.
To confirm the calibration: Press SAVE.
RAZ Val Factory
If necessary, to return to the factory calibration settings, press RETURN and then SAVE to record all settings.
