Cambridge Sensotec Rapidox 1100L Oxygen Analyser Instruction Manual
Low messages indicate that the sensor is out off normal range. The fault
message will only display if the sensor is disconnected or has failed in some
way.

Digital:
The digital signals coming directly from the computer chip inside
the analyser can be monitored here. To test the keypad is working correctly
try pushing the buttons and watching the panel. A correctly functioning
key will turn the box red on the screen and the digital value for that
particular key will show in the data box. If the analyser has an external
thermocouple correctly fitted (2100 and 3100 series only) then this will
display a signal in the “Temperature Sensor” box.

Log Diagnostic Data:
Checking this box will allow the software to log the
diagnostic data which can then be e-mailed to Sensotec for analysis. Do not
switch to a different tab while logging diagnostic data – the data is only
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.

Troubleshooting
Q:
The Rapidox says 'O/Range' and won't begin measuring.
A:
The sensor is not designed to measure oxygen above 10,000ppm so if the
machine has been switched off for a long time or the tubing has been
exposed to oxygen rich gas then please wait a while for the low oxygen gas
to flush through. After several minutes the message should clear and the
unit will start to take measurements.
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.
