Rapidox Analyser Menu System
All of the user-programmable functions are accessed via a menu system which is
controlled using the front panel Keypad (2). To access the menu press the ENT
button and to escape and return to the operating screen press ESC at any time.
The menu system flow chart is shown in Appendix 1 at the back of the manual.
6.2
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.
Turn the unit on using the red power switch on the front (5). The LCD (1) will
display the firmware version and then begin taking measurements. 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.
Push the gas sample tube (6mm OD/4mm ID) onto 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.
Allow five minutes for the box to stabilise fully. This allows the components of
the analyser to reach a stable working temperature. During this warm-up period it
is common for the baseline oxygen to drift by a small amount, which may be
corrected by re-calibrating.
6.3
Display Behaviour
Once at temperature the LCD display will show the oxygen reading (in percent or
ppm) on line 1 and the pressure (in mbar, bar, kPa, torr or psi) on line 2. The
symbol AL1 or AL2 may also appear in the bottom right of the LCD if the alarm
system is enabled and an alarm condition applies. The oxygen sensor reading
may flash, show U/Range or O/Range when its limits are reached, and error
messages will be displayed if there is a fault with the sensor. See Table 2 for more
details:
