Getting Started
Ensure that the Rapidox analyser is located away from extreme heat and dirt
environments. Plug the unit in to a suitable supply (noting the information on the
serial sticker and using the power cable supplied) using the rear power socket (8).
Make sure that the cooling fan (9) is not obstructed during operation.
Push the gas sample tube (6mm OD/4mm ID) to the GAS IN (3) connector and fit
the retaining collar hand tight. Repeat for the GAS OUT (4) connector should an
outlet tube be required. The pump will draw gas at a flow rate depending on the
value set either in the software or from the menu. The default setting is one
hundred percent.
Turn the unit on using the red power switch on the front (5). The LCD (1) will
display the firmware version followed by the message “HEATING SENSOR”. The
sensor will take approximately one minute to come up to temperature, after which
the Rapidox will begin to take measurements. The progress of the sensor heater is
shown in the form of a bar graph on the LCD (1). Once at temperature the LCD
display will show the oxygen reading and the pressure. The symbol AL1 or AL2
may appear to the bottom right of the LCD if the alarm system is enabled and an
alarm condition applies.
