logged while the “Diagnostics” tab is still selected. The software will log
diagnostic to a file named “Rapidox diagnostics file 210xxxx.txt” (where
“xxxx” is the serial number of the analyser) in the folder shown in the
yellow “Status” box at the bottom of the screen. Data is logged every 6
seconds, so the software should be left to run for at least 1 minute to gather
a few data points. In order to stop logging, simply uncheck the “Log
Diagnostic Data” tick box. Note that diagnostic data is always saved to the
same file, and will automatically overwrite any existing file without
prompting the user, so if you want to save existing data you must either
rename it or copy (or move) it to a different folder, before checking the “Log
Diagnostic Data” tick box again. If you are logging diagnostic data during
the analyser’s warm up period, the “Acquisition data:” box will display the
current sensor heating message, and will only display acquisition data once
the oxygen sensor has reached its operating temperature.
Once completed please e-mail this file to support@cambridge-

Troubleshooting
Q:
The Rapidox won't power up at all.
A:
There are fuses located on the power socket on both live and neutral lines.
These are standard 20mm 2A slow blow fuses available from a supplier
such as RS Components.
Q:
The Rapidox gives strange readings that are way off the expected values.
A:
Check to make sure which two calibration gases are selected. Are they the
same as the actual gases you used to perform the calibration? If not you can
change their values using the software. Also check to see that the pressure
correction mode is set to AUTO and that the ambient pressure is set
correctly.
Q:
The sensor does not read 20.9 - 21.0% in air (actual value is 20.95%).
A:
If the room air is very humid, it will slightly affect the observed
measurement or the sensor may have drifted slightly because of natural
ageing. If you are using air as a calibration point then simply do a quick re-
calibration in the air to compensate for this.
Q:
I messed up the calibration procedure and the analyser is not working
properly.
A:
Return the box to the factory defaults using the keypad or communications
software, by selecting ‘Default Configuration’ followed by ‘Write
Configuration to Analyser’ from the File menu. Now try re-calibrating the
Rapidox.
Q:
The software will not talk to the Rapidox.
A:
Make sure that you are using the correct cable, as supplied (pin 2 to pin 2
etc). A crossed RS232 cable (pin 2 to pin 3 etc.,) will not work. Make sure
