Sensor Lifetime and Replacing
When a new sensor is fitted the Rapidox analyser checks the output of the sensor
in air and stores the output characteristic of the particular sensor. All the sensors
are very slightly different to each other when manufactured but will have a life
expectancy of 3-5 years depending on the nature of use.
Over time the output of the sensor drifts slowly downwards until it is no longer
sufficient to work correctly. At this point a new sensor should be purchased and
installed. The analyser will warn the user when the time is getting close to
replace the sensor. This point is defined as 70% of the output when it was brand
new.
When the output drops to 70% of the new-value a warning message stating
“Replace Sensor Soon” will flash on the screen each time the unit is switched on.
If no action is taken and the output drops below 65% of the new-value then the
analyser will upgrade the message to say “Sensor Must Be Replaced”
Contact Cambridge Sensotec for advice on purchasing and replacing the sensor
inside the unit.

Printing
If you have purchased the printer option then you can print data from the analyser
straight on to thermal paper. Simply connect the printer to the serial socket on
the rear of the Rapidox and make sure the printer is switched on (battery and
mains versions are available). To print the live values on the LCD at any time
simply press the RIGHT arrow button on the front panel. Each press of the button
will print out the serial number followed by the data in a tabbed format followed
by a blank line. If the button is held down, the printer will keep printing data (but
not the serial number).
When the printer is first connected or turned on, a “start-up” message like the one
displayed on the LCD when the Rapidox is switched on will be printed, and will
